{"version":"1.0","type":"rich","title":"area chart","description":"This area chart visualizes electricity consumption against population for major cities, with the data sorted by population to show a clear upward trend. The chart uses blue filled areas beneath a yellow line, with orange points providing interactive tooltips that display additional city metrics. Built with D3 v7, the visualization loads CSV data from a GitHub gist, applies data-cleaning regex operations, and uses `d3.area`, `d3.line`, and `d3.curveMonotoneX` for smooth rendering. It also features grid lines, axis labels, and SVG animation for tooltip transitions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ff992f19e17e4d99b5250e4563b8765c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
