{"version":"1.0","type":"rich","title":"Customizing Axes","description":"This bar chart shows the top 10 most populous countries, using 2018 UN population estimates from the World Population Prospects. It demonstrates customizing D3 axes by removing domain lines, setting tick formats with `d3.format`, and adding axis labels. The code uses `d3.csv`, `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom`, rendering in SVG. Tick lines extend across the chart, and population values are formatted in billions with a custom replacement of 'G' with 'B'.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a7a85722ff8c4c9e98fc2c697a040db5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
