{"version":"1.0","type":"rich","title":"Bar Chart","description":"This example demonstrates a bar chart that loads population data from a CSV file and renders it as SVG rectangles using D3.js. The code uses `d3.csv` to parse the data, `d3.scaleLinear` to map population values, and `d3.select` with `append('rect')` for DOM manipulation. The resulting visualization displays raw rectangles without axes or labels, showing only the initial data-binding step. The chart is constructed with a fixed width and height for each bar, leaving the scaling incomplete.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
