{"version":"1.0","type":"rich","title":"Activity7_Q2","description":"This example displays an area chart comparing tree species by average height and lifespan, with two overlapping translucent regions representing each metric. It loads data from a CSV file hosted on GitHub Gist and renders the visualization as an SVG. The code uses D3 v7 APIs including `csv`, `scaleBand`, `scaleLinear`, `area`, `axisBottom`, and `axisLeft` to construct the chart. The `area` generator creates the filled paths, with categorical color coding—blue for height and orange for lifespan—and the chart adapts to the viewport size.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/88c2f26b75ac457f9bed38b5f2aeb020?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
