{"version":"1.0","type":"rich","title":"Making a bar chart","description":"This example demonstrates how to build a basic bar chart from a dataset of country populations. It loads data from a CSV file using `d3.csv`, parses the population values, and maps each row to a rectangle element in an SVG canvas. The code uses D3’s `select` and `scaleLinear` (though scaling is not yet applied), and appends `rect` elements with fixed dimensions inside a 960×500 SVG. The visualization serves as a starting point for showing raw data as simple blocks before adding axes or proportional scaling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
