{"version":"1.0","type":"rich","title":"Pathetic Bar Chart","description":"This example visualizes the ten most populous countries in 2020 as a horizontal bar chart, using bars that stretch across the screen without axes or labels. The chart loads UN population data from a CSV file via `d3.csv`, then processes each row to extract the 2020 population as a number. React’s `useState` and `useEffect` hooks manage the asynchronous data loading and component state, while D3’s `scaleBand` and `scaleLinear` position the bars along the y-axis and scale their widths. The bars are rendered as SVG `<rect>` elements using React’s declarative JSX syntax.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d5ad3ecd514749da80ad1d90038668b9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
