{"version":"1.0","type":"rich","title":"Fork of Let's make a face with D3.js!","description":"This visualization displays a treemap of particulate matter contributions by source type across three global regions. Each region is rendered as a separate SVG group positioned absolutely, with colored rectangles representing emission sources. The code uses D3.js v5's `d3.hierarchy` and `d3.treemap` to compute tile layouts, while `d3.select` and `d3.append` handle DOM creation. Colors are mapped to source categories via a predefined `typeColors` object, and the data comes from a static JSON file containing regional emission breakdowns.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/aa576d4aa0e44fd4b3c7d06960d5c13e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
