{"version":"1.0","type":"rich","title":"Barchart a.h.v tutorial Curran","description":"This example displays a horizontal bar chart of country populations from a CSV file, with each bar’s length proportional to its population value. The visualization uses D3 v5’s `csv`, `scaleLinear`, and `scaleBand` to map data to x and y positions, while `axisLeft` and `axisBottom` generate the axes. SVG rectangles are appended and styled with a teal fill via CSS. The chart includes margins and padding, and the population values are converted from strings to numbers with the unary plus operator.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c488e18c51404be8bc0d5fbce6727dba?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
