{"version":"1.0","type":"rich","title":"Making a bar graph using text file","description":"This example shows a bar graph of population by country, reading from a CSV file and rendering the data as SVG rectangles. The visualization uses D3 v7’s `csv` loader to parse `data.csv`, then a `scaleBand` for horizontal positioning and a `scaleLinear` for vertical population values. Blue bars are appended via `selectAll` and `join`, with heights computed from the y-scale. The page is a minimal HTML setup with React noted in metadata, though the code itself uses plain D3 with a container div.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a49a64b5aa054e408e062492f5096918?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
