blog » Hexbins! Binning is a general term for grouping a dataset of N values into less than N discrete groups. These groups/bins may be spatial, temporal, or otherwise attribute-based. In this post I’m only talking about spatial (long-lat) and 2-dimensional attribute-based (scatterplot) bins. Such binnings may be thought of as 2D histograms. This may make more or less sense after what lies beneath.

25 Innovative Dashboard Concepts and Designs Dashboard design is a tricky business. The challenge is to communicate the key numbers in a straightforward way, while allowing users to drill down into the specifics. It is about avoiding clutter, about catering for personalisation, and about the prioritisation of the right metrics. It’s difficult to get right, but I think many of these examples have lots of good things going for them. We’ve brought together a showcase of innovative, stunningly beautiful dashboard concepts & designs to help inspire you. If you’re about to start a project that deals with data visualization, hopefully this collection will give you some inspiration into how you can show your information in a useful, simple and uncluttered way.

24 beautifully-designed web dashboards that data geeks will love We live in a world of big (and little) data, and many people have to make sense of numbers as part of their job. The trouble is that there can be a lot of friction involved when mining the data. This is where dashboards come into play: a well-designed dashboard can save huge amounts of time, helping people to quickly identify the numbers that matter, in order to make insightful observations or to compile reports. Dashboard design is a tricky business. The challenge is to communicate the key numbers in a straightforward way, while allowing users to drill down into the specifics.

Crossfilter Fast Multidimensional Filtering for Coordinated Views Crossfilter is a JavaScript library for exploring large multivariate datasets in the browser. Crossfilter supports extremely fast (<30ms) interaction with coordinated views, even with datasets containing a million or more records; we built it to power analytics for Square Register, allowing merchants to slice and dice their payment history fluidly. Since most interactions only involve a single dimension, and then only small adjustments are made to the filter values, incremental filtering and reducing is significantly faster than starting from scratch. Crossfilter uses sorted indexes (and a few bit-twiddling hacks) to make this possible, dramatically increasing the performance of live histograms and top-K lists. For more details on how Crossfilter works, see the API reference.
