{"version":"1.0","type":"rich","title":"T1","description":"This pie chart visualizes the proportional distribution of entry-level, mid-level, and senior-level data professionals across geographic locations, based on aggregated salary and COVID-19 population density data. The chart aggregates population density values from `covid.csv` for each location, then uses `d3.csv` to load and `d3.group` to organize the data. Using `d3.pie` and `d3.arc`, the visualization renders SVG arcs with `d3.schemeCategory10` for color encoding, placing location labels at each arc’s centroid via `arc.centroid()`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7f0448d0f8ce4db2b1e4028a832fb255?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
