This interactive line chart displays EV charging station metrics across stations, letting users toggle between charging ports, average charge time, daily users, and monthly energy consumption via a dropdown menu. The visualization uses D3 v7 to load CSV data from a GitHub gist, sort stations by ID, and render an orange line with red point markers. Smooth transitions animate point position updates when switching metrics, while hover tooltips reveal station details. The chart includes gridlines, axis labels, and a cleaned axis without domain lines.
