{"version":"1.0","type":"rich","title":"Let's make a map with D3.js!","description":"This example uses a hierarchical dataset of world regions and countries to render a vertical tree diagram. The visualization displays the structure of continents, subregions, and nations as linked nodes using D3’s `tree` layout and `hierarchy` function. SVG paths connect parent and child elements with curved, vertical links generated by `linkVertical`, while the JSON data is loaded asynchronously via `json`. The chart adapts its dimensions to the browser window, with no interactive behavior beyond the static layout.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c331382c613445449540792407fb4aca?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
