The `d3.hierarchy` and `d3.treemap` layouts partition the data into rectangular cells that form eyes, nose, mouth, and head shape, all rendered as SVG elements. The visualization uses `d3.csv` to load the data and `d3.select` to bind it to the SVG container, with population values converted and scaled to drive the geometry.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/abe6c7cc6f6c4f2b96d28d46dca15be1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
