{"version":"1.0","type":"rich","title":"Area Chart","description":"This area chart visualizes rainfall measurements over time, with a smooth curve showing yearly rainfall trends and a blue-filled region beneath the line emphasizing the data’s magnitude. The chart uses D3 v5 with SVG rendering, employing `scaleLinear` for both axes, `area` and `line` generators with `curveBasis` smoothing, and `axisBottom`/`axisLeft` for ticks. Data comes from a CSV file loaded via `csv()`, with year and rainfall values parsed as numbers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d8920e112d27470ba4de006c50a7f333?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
