{"version":"1.0","type":"rich","title":"Area chart","description":"This area chart tracks electric vehicle sales in thousands over a sequence of years, using D3.js v7 with SVG rendering. The code loads a CSV dataset via `d3.csv`, sorts the data chronologically, and applies linear scales with `d3.scaleLinear` for both axes. It generates a filled area path using `d3.area` and overlays a stroked line with `d3.line`, plus data point circles. Axis labels and a bold title are included, with the chart drawn within a defined margin using the SVG coordinate system.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cd84dcfbe87549f7b431645e97a31fd8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
