Grouped BarChart
A grouped bar chart compares three industrial sectors—Electronics, Software, and Mechanics—across five European countries using data loaded from a CSV file. Each country displays three color-coded bars, with values labeled above and a legend on the right. Built with D3 v3, the chart uses ordinal scales for positioning, nested data rolls up values per country, and SVG transitions animate bars upward from the baseline upon load. Mouseover highlights bars in yellow, while hover-out delays the restoration of the original color.

This example has a bug that user can interupt the transition even through i add 'end' status at the end of it. Hoping one day i can find out.
The animation is a little uggly because the default animation behavous and my group layout. Whatever.
One thing to be mention, if you chain the selection, transition and on-event, it will not work. I think the chained returned selection is not appropriate for others.
