{"version":"1.0","type":"rich","title":"Untitled","description":"This visualization is a heatmap showing monthly property crime counts in San Francisco from 2005 to 2015. Each cell represents a month and year, colored on a viridis scale from low to high crime totals, with years on the y-axis and months on the x-axis. The code uses d3.nest and d3.map to aggregate the CSV data, d3.scaleBand for axes, and d3.scaleSequential with d3.interpolateViridis for the color encoding. A gradient legend with a d3.axisBottom is rendered using an SVG linearGradient.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1dd233f17d084619a0e1cc80f71aca19?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
