Much more accurate looking reflection of where we're at.
Plot the intra-sprint scope increase correctly
Plot the linear regression of the completed work

Needs to be clipped.
Calculate velocity
Date parsing fixes
Label fixes

Visualise burndown of the sprint
Add markers and clippaths
Include the start point of the iteration
Remove unrequired code
Periodically update the graph
Show the work that is maybe complete (blocking on AT)
Add a gradient for the work stuck in test
