{"version":"1.0","type":"rich","title":"Lesson 2","description":"A horizontal bar chart displays population estimates for a small set of countries, using data from the World Bank. The visualization renders as an SVG, with a linear scale mapping population values to bar widths and a band scale positioning each country along the vertical axis. Built with React and D3 v5, the code imports `scaleLinear`, `scaleBand`, `axisLeft`, `axisBottom`, and `csv` to load and draw the chart. Axis labels and axis tick formatting are generated through D3’s axis components.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/22d4d7821dce4da8972c0a3eeee6e86c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
