{"version":"1.0","type":"rich","title":"Show National Contiguity with a Force Directed Graph - D3.js","description":"This example visualizes national contiguity using a force-directed graph, where each country is represented by a flag sprite node and connections between bordering nations are shown as red links. It uses D3 v3’s `d3.layout.force` to simulate the physical layout, with nodes and links animated over time as the simulation runs. Hovering over a flag triggers a tooltip displaying the country name. The data is loaded asynchronously from a remote JSON file hosted on GitHub.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0841dea90d4343e19161abca260e2ba9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
