{"version":"1.0","type":"rich","title":"D3 Course 1: Bar Chart","description":"This bar chart displays population figures for ten countries, from China at over 1.4 billion down to Mexico at 130 million. The visualization uses D3 v5 with a promise-based data-loading pattern, where `csv` fetches `data.csv` and multiplies each population value by 1,000. The SVG rendering employs `scaleLinear` and `scaleBand` for axes, with `axisBottom` and `axisLeft` to draw ticks and gridlines. The chart formats population labels as abbreviated values with a custom tick formatter that replaces \"G\" with \"B\", and removes the domain lines for a cleaner look.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6bc98bba57a84229bc296346418a6335?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
