Target concept: Ascending unemployment–inflation curve construction: the curve slopes upward from the lower left to the upper right (a simplified charting convention specified by the prompt — not the real-world short-run Phillips trade-off, which is empirically an inverse, downward-sloping relationship).

Video generation prompt: Display a graph with the unemployment rate on the horizontal axis and the inflation rate on the vertical axis. Adjust the unemployment rate in ascending order and plot the corresponding points of the inflation rate, then connect these points to form a curve.

Evaluation guide:
Target concept: Visual construction of a labeled unemployment–inflation chart in which the plotted points ascend monotonically in both variables, producing an upward-sloping curve when unemployment (x-axis) increases alongside inflation (y-axis). This is the specific geometric construction requested by the prompt; it is a simplified, illustrative pairing convention and does NOT represent the historically-observed short-run Phillips trade-off, which is empirically an inverse (downward-sloping) relationship between unemployment and inflation. Minimum mechanistic assumption: For demonstration purposes only, the mapping from unemployment to inflation is treated as deterministic and monotonically increasing (each ascending unemployment value pairs with a strictly larger inflation value) so that an unambiguous upward curve can be drawn; this pairing rule is a construction convention for this video, not a claim about real economic data. Phased storyline: (1) Static graph initializes with labeled axes; (2) First point plots at lowest unemployment (e.g., 3%, 1.2%); (3) Subsequent points appear left-to-right, each at higher unemployment and higher inflation; (4) A continuous curve draws incrementally, linking points in order; (5) Final frame shows complete upward-sloping curve spanning lower-left to upper-right. Visibility constraints: All labels must be legible at native resolution; no occlusion; curve must be discernible against background without motion blur; perspective is front-facing 2D graph, with no rotation, depth, or 3D projection.

I. Basic Demonstration Information
Demonstration Title: Stylized Ascending Unemployment–Inflation Curve Construction (Simplified, Non-Canonical 'Phillips Curve' Convention) Demonstration
Subject: Economics - Macroeconomics - Inflation and Unemployment
Demonstration Purpose: To visually construct a labeled Cartesian chart in which unemployment (x-axis) and inflation (y-axis) are plotted as an ascending pair sequence, producing an upward-sloping curve, exactly as the prompt's construction rule specifies — this is a pedagogical charting exercise, not a claim about the true short-run Phillips relationship (which is empirically inverse).

II. Demonstration Carrier/Equipment
Core Carrier: Dynamic Cartesian graph interface (digital, vector-based, high-contrast)
Auxiliary Equipment: Clean white background; sans-serif bold axis labels; numeric tick marks (x: 3–9% in 1% steps; y: 1–5% in 0.5% steps); animated plotting cursor; smooth curve-drawing tool.

III. Demonstration Content Description
Layout: Full-screen centered graph with origin at bottom-left; x-axis labeled 'Unemployment Rate (%)', y-axis labeled 'Inflation Rate (%)'; both axes extend visibly beyond the plotted range.
State Control: Unemployment values progress strictly ascending: 3% → 4% → 5% → 6% → 7%; for each, the inflation value is deterministically higher than the prior point (e.g., 1.2% → 1.8% → 2.5% → 3.3% → 4.1%), per the construction convention described above.
Comparison Baseline: Each plotted point snaps precisely to its integer-percent unemployment value and matching inflation coordinate; the curve connects points with a continuous, unbroken line.

IV. Observation of Core Phenomena
Expected Phenomenon: As unemployment increases left-to-right along the x-axis, plotted points rise steadily upward along the y-axis; the connecting curve forms an unambiguous upward trajectory from lower-left (3%, 1.2%) to upper-right (7%, 4.1%).
Expected Screen: Static graph frame; animated sequential plotting (no simultaneous appearance); curve draws progressively, never retroactively.
Visual Verification Features: (1) Axis labels fixed and legible; (2) Unemployment ticks strictly ascending with equal spacing; (3) Inflation values strictly increasing; (4) The final curve has a clearly positive slope, passing through all points without inflection or descent; (5) No visual ambiguity — the curve must be clearly distinguishable from a horizontal, diagonal-descending, or flat line.

V. Summary of Key Knowledge Points and Principles
Core Concept Definition: The real-world short-run Phillips relationship is an empirically observed INVERSE association between unemployment and inflation (historically, lower unemployment is associated with higher inflation, and vice versa) — the opposite of the shape drawn in this demonstration.
Economic Significance: This demonstration deliberately uses a simplified, monotonically-ascending pairing (unemployment up, inflation up) purely as a charting and curve-construction exercise, exactly as the posted prompt instructs. It should be read as an exercise in axis labeling, sequential point-plotting, and curve construction — not as an assertion about real macroeconomic data or the historical Phillips trade-off. Evaluators should judge the video on correct axes, correct ascending-pair construction, and the resulting upward curve shape, without reading any real-world inverse-relationship claim into it.

VI. Demonstration Precautions
- Never swap the axes or invert the y-axis.
- Never let inflation decrease while unemployment increases — that would break the ascending construction rule this specific demo calls for.
- Avoid curve segments that dip below a prior point or flatten out.
- Make the final curve clearly visible against the background, drawn in a solid, high-contrast color (e.g., royal blue) that is visually bolder than the axis lines.
- Keep total animation duration at or under 10 seconds: roughly 1.5s per point plus about 2s for the full curve reveal.

Prompt Grounding rubric:
level_1: No graph is displayed; or the axes are missing/mislabeled (e.g., inflation plotted on the x-axis, unemployment on the y-axis); or the plotted markers show no ascending unemployment sequence; or no connecting curve appears, or the curve is flat/descending; the chart shows zero resemblance to the ascending unemployment-inflation construction the prompt calls for.
level_2: A graph is present, but with major faults: one axis is correctly labeled while the other is swapped or unlabeled; unemployment values increase but not strictly (e.g., jumps or reversals such as 5%→4%→6%); inflation markers appear but are left unconnected, or connected by a line that is flat or trends downward; only minimal resemblance to the intended upward-sloping curve.
level_3: Graph shows correct axis labels ('Unemployment Rate (%)' on x-axis, 'Inflation Rate (%)' on y-axis) and at least 3 plotted markers; unemployment values ascend strictly across markers (e.g., 3%, 5%, 7%); markers are connected by a line; however the line is visibly non-monotonic (e.g., dips then rises) or its overall slope from lower-left to upper-right is ambiguous.
level_4: Graph correctly displays unemployment (x-axis) and inflation (y-axis) with numeric tick marks (e.g., 3%–7% on x, 1%–4% on y); at least 4 markers plotted in strict ascending unemployment order; markers connected by a smooth, continuous line with an unambiguous upward slope from lower-left to upper-right; only minor cosmetic flaws remain (e.g., an axis title slightly cropped, one tick label in a different font, faint/missing gridlines).
level_5: Fully compliant: a clean Cartesian chart with bold, centered axis titles 'Unemployment Rate (%)' and 'Inflation Rate (%)'; 5–7 markers plotted at evenly spaced ascending unemployment values (e.g., 3%, 4%, 5%, 6%, 7%) paired with strictly increasing inflation values (e.g., 1.2%, 1.8%, 2.5%, 3.3%, 4.1%); markers joined by a single smooth, unbroken, upward-sloping line passing through every marker; no stray marks, occlusions, or labeling errors anywhere in the frame.

Scientific and Causal Correctness rubric:
level_1: No coherent construction sequence is shown: the curve appears fully formed with no point-by-point buildup; or an inflation value decreases as its paired unemployment value rises even though the prompt calls for an ascending pairing; or the points and curve bear no visible link to the unemployment values shown.
level_2: A construction sequence is attempted but is logically incoherent: points appear in random unemployment order and are only afterward sorted/connected; or an inflation value decreases while its paired unemployment value increases; or the full curve is drawn before any individual points are placed.
level_3: Points are plotted in the correct order as unemployment ascends, but at least one inflation value fails to increase relative to the previous point (e.g., 2.0% → 1.9% → 2.3%), and the curve nonetheless connects them as if the sequence were monotonic, showing the plotting mechanics without consistently enforcing the ascending-pair construction rule.
level_4: Unemployment values advance stepwise left-to-right; each new marker appears only after the previous marker is fixed in place; the paired inflation value increases with every step, with no exception; the curve extends incrementally as each new marker is added, but no distinct visual cue (e.g., a brief highlight or connecting tick) marks the moment a given unemployment value determines its paired inflation value.
level_5: The construction is fully causal and legible in real time: (1) each unemployment value is placed first and visibly precedes its paired point, (2) the corresponding inflation marker appears immediately after, always higher than the previous inflation marker, (3) each marker locks onto its correct (unemployment, inflation) coordinate, (4) the curve segment to that marker is only drawn once the marker is fixed, so a viewer can read off, step by step, that rising unemployment is paired with rising inflation exactly as the prompt's construction rule specifies, with no reversal or skipped step anywhere in the sequence.

Spatiotemporal Consistency rubric:
level_1: Severe spatiotemporal breakdown: axis labels appear and disappear erratically; markers jump directly onto the chart instead of animating into place; the curve visibly draws backward or flickers on and off; markers appear out of unemployment order (e.g., the 6% marker appears before the 4% marker); the chart's position or scale changes abruptly between frames.
level_2: At least one moderate discontinuity: an axis label shifts position mid-sequence; markers appear with visibly inconsistent pacing (e.g., one marker appears almost instantly while another takes several seconds with no clear reason); the curve is drawn in visibly disjointed segments with gaps, or is redrawn from scratch partway through; the chart drifts sideways or resizes during the animation.
level_3: The chart frame stays fixed in size and position; markers appear in left-to-right unemployment order at a roughly steady pace; the curve connects markers with no visible gaps once drawn; minor imperfections are allowed (e.g., a marker settles into place with a small wobble, or the curve's line weight varies slightly), but the overall ascending sequence and layout remain clearly legible throughout.
level_4: All conditions for score 3 are met, and additionally: the chart's origin, axis scale, and aspect ratio stay constant for the full clip; markers appear at a visually even, predictable pace (roughly one per second); each marker settles into its final position without overshoot or bouncing; the curve is drawn with a steady, constant-looking stroke width and speed; no marker or axis label drifts or resizes at any point.
level_5: All conditions for score 4 are met, and additionally: the chart occupies a stable, clearly framed region of the screen for the entire clip; the sequence of unemployment values advances at an even, evenly-spaced pace with no rushed or stalled segments; each marker's appearance (e.g., a brief settle-in motion) looks the same for every marker; the curve's drawing speed and thickness stay visually constant from the first segment to the last; there is no stutter, skipped frame, or unexplained jump anywhere in the full sequence.
