{"version":"1.0","type":"rich","title":"Dataviz 2018 - 3. Bar Chart - D3 CSV Data Import, Data Joins, Scales, Margin Convention, Axes - Ep7","description":"This example shows a horizontal bar chart of population estimates for ten countries, imported from a local CSV file. It demonstrates core D3 v7 techniques including `d3.csv()` for tabular data import, data joins via `selectAll().data().enter()`, and `scaleLinear` and `scaleBand` for positioning. The margin convention establishes an inner plotting area, and axes are added using `axisLeft` and `axisBottom`. The chart renders as SVG with steelblue rectangles, and population values are scaled by 1,000 during preprocessing.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f316d1ceb7f1494c98eab1846e7a143b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
