- Svelte set of libraries used to generate maps via code.\nMapserver and friends are all huge hulking beasts. Think of Mapnik as a drawing API for making maps.\n

- Very similar to photoshop...\nBuild up canvas, add data from layers (text, raster, vector), add styles to layers (XML, CSS like languages), decide output formats\nrender.\n

- Mapserver\nGeoserver\nArcGIS Server\netc...\n
- Free\nWell supported and maintained, it's in the GSOC (CartoCSS support, Advanced Labelling and Windows support are 2011 projects), large community - OSM, IRC, Mailing lists\nWonderful API integration with Python, but more importantly, Node.js\n
