{"version":"1.0","type":"rich","title":"Fork of arrow","description":"This visualization shows a force-directed network graph where nodes represent countries involved in migration or refugee flows, with link weights indicating the strength of connection. The node color reflects a measure such as PageRank, and the graph can be interactively dragged. The visualization uses the D3.js library, specifically its `d3.forceSimulation` and `d3.drag` APIs, running on SVG. Data is loaded from a JSON file, with links and nodes positioned dynamically by the simulation. The code also defines a marker for line endpoints, and includes a stylesheet for visual styling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4c7b1e50fe834ce28f4ee59941735294?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
