Spreadsheet task (Chart Creation):
1. Create a chart titled "Chart A Scores". Each row of data from the Chart A column should appear as a single square marker positioned along a fixed horizontal 0–10 axis, with all rows stacked vertically (first row at top, last row at bottom). Color each marker based on its value: Red if <3, Yellow if ≥3 and <8, Green if ≥8. Include a thin horizontal grey guideline spanning the full axis width for each row. Label the left end of the scale endpoints as "Low" and the right end "High" for each row and suppress all numeric axis labels and gridlines. Place the chart title at the top centre.

2. Create a chart titled "Chart B Scores". Each row of data from the Chart B column should appear as a point positioned along a horizontal 0–10 axis, with all rows stacked vertically in their original order (first row at top, last row at bottom). Connect all points with a single continuous line in soft green. Label the left end of the axis "Low" and the right end "High," and suppress all numeric axis labels and gridlines. Place the chart title at the top centre.
