{"version":"1.0","type":"rich","title":"activity 7.1 question 2","description":"This example shows an area chart of average clothing weight by size. The visualization loads CSV data from a GitHub gist, groups the records by clothing size, and computes the mean weight for each category before drawing the chart using D3 v7. The SVG rendering uses `d3.scaleBand` for the categorical x-axis, `d3.scaleLinear` for the y-axis, and a `d3.area` generator to create the filled path. Axes are added with `d3.axisBottom` and `d3.axisLeft`, and the chart is styled with steelblue fill.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6fb420343c5343e49486be3e14a6703a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
