Testing Crossfilter following two tutorials: "explore your multivariate data with crossfilter" & "crossfilter tutorial". Also consulting the API reference.
WARNING: displaying the demo could hang your tab, browser or even your entire device (since the earlier is really heavy due to associated data: ~52 MB (~13 MB gzipped)). I recommend to save every work in progress at every single application which you were working on your device before checking the demo otherwise you may lose unsaved data. I also discourage use mobile data to access this demo and look for a Wi-Fi connection instead.
If once you have read and understood this disclaimer you still want to check the demo, enter here.
