Scale Bars for D3 Maps

Full Screen

Scale bars help viewers understand the geographic extent of maps. Printed maps, even those produced over a century ago, seldom lack them, yet scale bars are commonly missing from modern maps published on the internet. d3-geo-scale-bar makes it easy to add scale bars to maps created with d3-geo, a popular open source library for publishing maps on the web.
