{"version":"1.0","type":"rich","title":"Introduction to D3","description":"This example presents a bar chart of country populations using a simple SVG and a small dataset. Built with D3 v6, it loads population data from a CSV file and renders a horizontal bar chart. The code uses `d3.scaleLinear` for the quantitative x-axis, `d3.scaleBand` for categorical y-axis, and `d3.axisLeft` with `d3.axisBottom` to draw chart axes. The visualization demonstrates basic D3 syntax for data binding, scaling, and SVG element creation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1fb31a6870a24b6e9179fcc60a03f203?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
