{"version":"1.0","type":"rich","title":"Question4_Ice7","description":"This visualization shows temperature trends over time for multiple cities using overlapping area charts. Each city’s temperature series is rendered as a filled, semi-transparent region with a colored stroke, and a legend identifies each city. The chart loads CSV data from a GitHub gist, converts dates to JavaScript Date objects, and draws the areas with `d3.area()` using a monotone curve, with scales set by `d3.scaleTime()` and `d3.scaleLinear()`. Axes are added via `d3.axisBottom()` and `d3.axisLeft()`, and colors come from `d3.schemeTableau10`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e825656068874c9aa04358db7b5a5296?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
