{"version":"1.0","type":"rich","title":"07 - let's make a bar chart - dataviz 2018","description":"This bar chart displays the population of the top 10 most populous countries using 2018 estimates from the United Nations World Population Prospects. The visualization uses D3 v7’s `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to map population values to horizontal bar lengths and country names to vertical bands. Data is loaded from a CSV file via `d3.csv`, with population values multiplied by 1,000 during preprocessing. The SVG rendering applies a steelblue fill to bars, with margins and axes configured to organize the categorical comparison clearly.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b93a4d3843ef4852b4ddb2f05deda4a0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
