{"version":"1.0","type":"rich","title":"Top 3 Largest Cities","description":"A horizontal bar chart displays the population of the top three largest cities—Shanghai, Mumbai, and Sao Paulo—based on 2018 data from the United Nations World Population Prospects. The visualization renders as SVG, using D3 v5’s `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to map population counts to bar widths and country names to vertical bands. Data is loaded from a CSV file via `d3.csv`, with values parsed as numbers. Green rectangles encode each city’s population, and axes are labeled with default text formatting.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b03e5be1e84c435e8139019ff41b26ec?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
