{"version":"1.0","type":"rich","title":"D3 Starter","description":"This example demonstrates a minimal bar chart template using D3, rendering four country population values as equal-sized squares. The SVG canvas is initialized with fixed dimensions, and the code loads data from a CSV file via `d3.csv`. Each rectangle is appended using the data join pattern (`.selectAll('rect').data(data).enter().append('rect')`), though all bars share the same 300×300 size. The visualization relies on D3 v6’s module imports, `select` and `csv`, to process the data and update the DOM without any scales or axes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/40a71415d95e49bbb6c5c3f84c8983d5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
