{"version":"1.0","type":"rich","title":"making a barchart w d3.js and svg","description":"A React and D3.js bar chart displays population data as horizontal bars using SVG. The visualization maps each country to a vertical band via `d3.scaleBand` and population to horizontal lengths with `d3.scaleLinear`, annotated by `d3.axisLeft` and `d3.axisBottom` axes. Data is loaded from a gist CSV file, then parsed and scaled, rendering steel blue rectangles inside a 960x500 SVG. The code uses D3 v5 imported as named modules, with selectors and attribute chaining to build the chart.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/45c5e02eabd3445988046f112272eb48?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
