{"version":"1.0","type":"rich","title":"Project_2","description":"A choropleth-free, year-wise grouped bar chart visualizes COVID-19 metrics—total cases, deaths per million, and population density—for a user-selected country. The interactive dropdown filters data loaded from `cleaned_covid_data.csv`, using `d3.csv` with time parsing. Rendering in SVG, the chart employs `d3.scaleBand` for grouped bars, `d3.axisBottom` and `d3.axisLeft` for axes, and tooltips that display values on hover. Population density, often dwarfing case/death counts, shares the y-axis, revealing scale discrepancies across years.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8ac0da6bc55c455fb6fb7c6c68dc368a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
