{"version":"1.0","type":"rich","title":"Making a Bar Chart with D3.js","description":"This example demonstrates a basic bar chart built with D3.js, mapping country populations from a CSV file to SVG rectangles. The code uses `d3.csv` to load the data, `d3.scaleLinear` for scaling, and `selection.enter()` to append rectangular elements. The chart reads the data.csv file, multiplies population values by 1,000, and renders static 300-by-300-pixel bars without axes or labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
