{"version":"1.0","type":"rich","title":"A7 -D3 Heat Map","description":"This heat map visualizes historical Valentine's Day spending across multiple categories and years, with darker colors indicating higher values. The visualization loads data from a CSV file and renders it as an SVG using D3 v6, employing `d3.scaleBand` for the categorical axes, `d3.scaleSequential` with the Inferno color scheme, and interactive tooltips on mouseover events. A color legend on the right helps interpret the spending scale.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/aa3f3ede813841aa819a7d803b619cc4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
