    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!
