Demo of CartoDB's SQL querying capabilities through its JavaScript API. Example is based on stock example code.

This choropleth map shows municipalities with a population > 100000. See the unfiltered map here.

Dataset comes from Dutch census data as delivered by this PDOK WFS endpoint. Get the data as GeoJSON by downloading OGR and executing

ogr2ogr -f GeoJSON municipalities2011.geojson WFS:"http://geodata.nationaalgeoregister.nl/wijkenbuurten2011/wfs" gemeenten2011 -t_srs EPSG:4326

CartoDB also supports dynamic styling!

Better Living Through Documentation

http://datamade.us/blog/better-living-through-documentation/

A thorough list of recommendations on how to write developer-friendly documentation (and best practices). Contains many useful tips e.g. "don't put important content directly before or after a code snippet", "avoid the word 'just'" and "make sure code examples are okay to copy/paste".

OpenLayers 3 examples

http://openlayers.org/en/v3.8.2/examples/cluster.html

Executes the "easy copy/paste of code" mantra extremely well. Code is copied to clipboard or JSFiddle with a single click. The latter is extremely useful for doing quick, one-off experiments.
