{"version":"1.0","type":"rich","title":"Basic Map Scale Bar","description":"A map of Australia rendered with a conic equal-area projection in D3 v4 uses a dynamic scale bar in the lower-left corner. The scale bar automatically measures the physical distance across the center of the map, adjusting its pixel width until the corresponding distance is a clean, round number, then labels it in kilometers or meters accordingly. The map itself uses TopoJSON data with green landmasses and white country boundaries, while the scale bar is constructed from alternating dark and light rectangles with rotated distance labels and a unit caption.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-7e2096170ae87ce85ee0455fe959e376?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
