{"version":"1.0","type":"rich","title":"Temperature In SanFrancisco : LineChart","description":"This example visualizes earthquake counts across U.S. states from 2010 to 2015, broken down by magnitude category. A dropdown menu lets users switch between categories, updating a heatmap of colored rectangles. The visualization uses d3.csv to load data, d3.scaleBand for axes, d3.scaleQuantize for the color scale, and d3.axisLeft and d3.axisBottom for chart axes. Hovering over a cell reveals its exact count via a tooltip, and a legend shows the color-to-value mapping.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/751968cc1fe141b085e0a93d56782526?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
