CHT-005

Two-period comparison

  • Bars grow in turn and the change pops up above them.

Make a grouped bar chart comparing two periods side by side. The previous period is a faint grey and this period is [accent colour]. Bars grow group by group, and when they finish the change pops up above them, green when it rose and pink when it fell.

[paste your table here]

The first row is the header. Put CSS and JavaScript in a single HTML file and draw with canvas or SVG, without external libraries. Dark background, crisp numbers and text, and no overlapping text even at phone width. If prefers-reduced-motion is on, show the finished chart without motion.
