{"version":"1.0","type":"rich","title":"Question 2","description":"A city-by-city temperature comparison appears as an area chart, with a single smooth region filled beneath the curve to highlight overall values across categorical x-axis labels. D3 v7 loads CSV data from a GitHub gist via `fetch` and `d3.csvParse`, then builds an SVG with `d3.scaleBand` for the cities on the x-axis and `d3.scaleLinear` for temperature on the y-axis, using `d3.area` to generate the filled path. Rotated city names and labeled axes (“Temperature (°C)” and “Cities”) clarify the mapping, while the rendering relies on standard SVG elements and D3’s `axisBottom`, `axisLeft`, and `scaleOrdinal` APIs.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/275254f1fcd14fdaa1ce4c7102e659b7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
