Fork of Playing with D3 and Gantt
This fork of “Playing with D3 and Gantt” presents an interactive Gantt chart tracking date ranges for a list of countries. It displays horizontal bars on a timeline, with a brushed mini-map below for zooming and a vertical current-line indicator. The visualization uses D3 v6 APIs including `scaleTime`, `scaleLinear`, `brushX`, `axisBottom`, and SVG transitions. Country data is hardcoded in a separate module, and the chart responds to window resizing while supporting mouseover tooltips via appended HTML divs.
