A Bird's Eye View of ClojureScript
summary
A migration-visualizer called Birdwave is built with ClojureScript, Om, d3 and Pedestal, importing a lazy-parsed eBird dump of 11 gigs of text into Datomic and exposing a REST API. Client-side code uses D3 topo/geoJSON, a month slider, Flickr search integration and core.async; partitioning limits queries to a species (about 1,700 species in the dataset) and avoids rendering thousands of DOM nodes by switching from county to state data to stop rendering 3,000 SVG elements.
