{"version":"1.0","type":"rich","title":"  area chart","description":"This area chart visualizes yearly data from a CSV file, showing how values change over time. It loads the dataset via `d3.csv` from a GitHub Gist, parses the year and value columns, and renders a filled steelblue area using the `d3.area` generator. The chart uses linear scales for both axes, with an x-axis formatted to show integer years and labeled \"Year,\" while the y-axis is labeled \"Value.\" Axes are drawn using `d3.axisBottom` and `d3.axisLeft` within an SVG container, demonstrating basic data loading, scaling, and shape generation in D3 v7.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ee97e72e0b274aa5b6256b983049a58d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
