{"version":"1.0","type":"rich","title":"Stack Overflow - Calendar Heatmap","description":"This example displays the daily number of answered posts on Stack Overflow as a calendar heatmap, using a color scale to represent the intensity of activity across dates. The code is built with D3.js v5, using `scaleLinear` and `scaleBand` to render rectangles within an SVG, and includes date-range pickers via the TheDatepicker and jQuery UI libraries for interactive filtering. The data consists of a sample CSV with date and answer count pairs, which are mapped to the heatmap grid for visualization.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e4ef315b3a30465ca9239811bf504b98?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
