{"version":"1.0","type":"rich","title":"My bar chart","description":"This example shows a horizontal bar chart of national populations with bars proportional to each country’s population value. The chart renders as SVG rectangles positioned within a fixed 960-by-500 viewport using D3 v5’s `select`, `append`, and `scaleLinear` APIs. Population data loads from a CSV via `d3.csv`, with values multiplied by 1,000 before mapping through a linear scale. The underlying framework emphasizes fundamental DOM manipulation techniques demonstrated in the accompanying video.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7c387bc8001d4cdb9b5e7a7eb09e796f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
