{"version":"1.0","type":"rich","title":"Activity 7: Area Chart","description":"An area chart displays battery life versus screen size across phone categories. The chart uses semi-transparent, color-coded areas for each category, which are differentiated by a legend. Data is loaded from a CSV file using `d3.csv` and rendered as SVG with D3 v7. The visualization uses `d3.scaleLinear` for axes, `d3.scaleOrdinal` with `d3.schemeTableau10` for colors, and `d3.area` with `d3.curveMonotoneX` to create smooth, filled areas for each category.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6e5f9eb3a1574931915fb5a418286ef0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
