{"version":"1.0","type":"rich","title":"area chart","description":"This interactive area chart visualizes EV charging station metrics—charging ports, average charge time, daily users, and monthly energy—across station IDs. Built with D3 v7, it renders a smooth area path with an overlaid orange line and circular points, all using SVG. A dropdown menu lets users switch between metrics, triggering transitions that update the axes, grid, and data points. Hovering over a point reveals a tooltip with city details and the selected metric’s value, with data loaded from a remote CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bfc3783c886e4db9829324b7e99ff5ac?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
