{"version":"1.0","type":"rich","title":"activity7.1.2","description":"An area chart displays the average temperature for each condition category. The visualization uses a D3.js `area` generator to draw the shaded region, with a `scaleBand` for the categorical x-axis and a `scaleLinear` for the y-axis. The SVG chart loads CSV data from a GitHub gist, groups it by condition, and computes mean temperatures. Axis labels and a steelblue fill are applied, with axes rendered using `d3.axisBottom` and `d3.axisLeft`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/50a4032fe3054b389f4664274c53bdb2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
