{"version":"1.0","type":"rich","title":"Paths between named points","description":"A map of India renders city markers and orange curved arcs between them, using D3 v4 with an SVG Mercator projection. City coordinates are loaded from a JSON dictionary and plotted as circles, while routes between pairs of cities are drawn as quadratic arcs using a custom `lngLatToArc` function that computes curved paths from projected source and target points. The map is layered with a green semi-transparent GeoJSON shape of India beneath the arcs and city points.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-df9dfa52f7ca020439b03047d29ce9c3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
