I find it a bit confusing that the bars on this chart go down, rather than up. I can see why, if you're looking at it as a subtraction from zero, but do our brains work that way? We say that hiring costs are going "up", we say "increasing overall payroll expenses 176% year over year to $70.8k per month" , and the "Total payroll for the year" heading shows a positive number. All up words. Yet the bars go down.
Perhaps those contradictions aren't confusing to finance people, but I'd find it much easier to interpret this graph if it showed positive rather than negative numbers.
Behavior gets really weird when I drag these faces off the left or right side. Might want to clip interpretation of mouse position to the visible edges.
Like how the heads bunch up? Yeah it feels bad — it’s unintentional and uninvertible! (Well, you can painstakingly move individual heads apart by clicking and dragging very low near the axis.) It's tricky that where to clip would depend on the vertical position of the mouse, too. Could also just *not* clamp head position to extent of timeline, but then once you released them you couldn't see them or easily bring them back, which is a different sort of uninvertibility
It should probably keep track of the original positions from mousedown, and then compute new positions during the drag based on the relative mouse position.
