{"version":"1.0","type":"rich","title":"Project Task 3","description":"A bubble chart plots the first 30 countries from a CSV dataset, comparing COVID-19 total cases per million on the x-axis against population density on the y-axis. The circle sizes encode consumption values, and color distinguishes each country via d3.scaleOrdinal with d3.schemeCategory10. Interactive tooltips display exact values on mouseover. The visualization uses D3 v7 (d3.csv, d3.axisBottom, d3.axisLeft) with SVG rendering, filtering out countries with population density over 1000.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/708ee25533104f669ed0de95c525629b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
