Showcase: Live JavaScript Data Grid Demos
24 whole applications, each built on Lattice Grid over a real public dataset: government open data, live weather and transport feeds, financial and scientific statistics. Every one runs live on GitHub Pages, with its full source in its own repository. Not a feature in isolation, the way a demo on this site's own demos page is, but a small, real application you can read start to finish.
