{"version":"1.0","type":"rich","title":"Customizing Axes","description":"This bar chart displays the populations of the top 10 most populous countries, based on 2018 estimates from the United Nations World Population Prospects. It shows how to customize D3 axes by removing default domain lines and tick marks, adding custom axis labels and a title, and formatting tick values using the `format` API to abbreviate large numbers (e.g., converting billions to “B”). The chart uses `scaleLinear` and `scaleBand` for positioning, with `axisBottom` and `axisLeft` for rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/370c3e6126bb48458fc105877d8f7d9c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
