{"version":"1.0","type":"rich","title":"lesson 8: Bar chart","description":"A bar chart displays population estimates for ten countries, from China at roughly 1.4 million to Mexico at 130 thousand, using data loaded from a CSV file. The React app uses the `useState` and `useEffect` hooks to fetch the data with `d3.csv`, converting population values to numbers. Victory’s `VictoryChart` and `VictoryBar` components render the bars, with country names on the x-axis and population on the y-axis, styled via a custom tick label font size and chart padding.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8feba9c228c348c3b80eb9bf219b37bd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
