{"version":"1.0","type":"rich","title":"Making a Bar Chart","description":"A bar chart displays population estimates for thirteen countries and two placeholder entries, with bars sized by population and colored on a red gradient. Hovering over a bar updates an HTML overlay with the country name and value. A green circle toggles an animation that transitions all bar widths between zero and their original lengths using a custom `transitionWidth` function. The visualization uses D3 v5 APIs including `scaleLinear`, `scaleBand`, `axisLeft`, `axisBottom`, and `.transition()`, with SVG rendering and data loaded from a local CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/55bf6d0ddb1f4500a0eeabda8c6a85ca?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
