{"version":"1.0","type":"rich","title":"Area Chart Visualization","description":"This area chart visualizes iPhone user growth from 2007 to 2017 using a smooth curve generated by D3’s `area` and `line` generators with `curveBasis`. The SVG renders a filled purple region beneath a black stroke, with green tick labels and orange grid lines via `axisBottom` and `axisLeft`. Data loads from a CSV using `csv` and scales with `scaleLinear` for both axes. The code imports modular D3 v5 functions like `select`, `extent`, and `format`, illustrating a combined line-and-area chart pattern.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/079b0d3b45224f87863006847ab946bf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
