Some of my favorite data visualization resources

Pretty much everything that contains the words visualization and data in the title is getting my attention. Moreover so if it promises a list of resources that could help me learn a bit of the art of visualization. Aaron Cordova’s list contains books, sites, and tools:

Visualization is more art than science at this point, although some have used it enough to be able to identify successful techniques for various purposes. Most successful visualizations are perhaps more dependent upon the decision or task at hand than the actual original structure of the data.

A Tour Through the Visualization Zoo

I’ve been looking for such a resource for quite a bit of time. Yesterday I’ve run into the article signed by Jeffrey Heer, Michael Bostock and Vadim Ogievetsky from Stanford University which provides:

A survey of powerful visualization techniques, from the obvious to the obscure.

Everyone’s recommending Edward Tufte’s The Visual Display of Quantitative Information. After reading it, I realized that I was expecting something else.. This article is what I was looking for.

Linkurious: Visualize Graph Data Easily

Nice tool for visualizing and exploring graph databases:

linkurious-screenshot-12-e1354194477174

Currently it supports only Neo4j, but it can be extended to other graph databases.

Rickshaw: Interactive Time Series Graphs JavaScript Toolkit

Rickshaw is a JavaScript library providing the elements needed to create interactive time series graphs: renderers, legends, hovers, range selectors:

Rickshaw Scatter plot with multiple series

The Richshaw example page lists many other visualizations.

Gallery of Named Graphs

Wikipedia: some of the finite structures considered in graph theory have names, sometimes inspired by the graph”s topology, and sometimes after their discoverer.

Strongly regular graphs

Even if you’re not into graphs, graph databases, or graph processing, some of these are truly beautiful.

Visualizing Systems Behavior: Subsecond Offset Heat Maps

This one is for ops, devops, noops and everyone else that loves some state-of-art real-systems behavior visualizations and investigation:

The subsecond offset heat map puts time on two axes. The x-axis shows the passage of time, with each column representing one second. The y-axis shows the time within a second, spanning from 0.0s to 1.0s (time offsets). The z-axis (color) show the count of samples or events, quantized into x- and y-axis ranges (“buckets”), with the color darkness reflecting the event count (darker == more).

Different Graph Visualization Models: Graphs Beyond the Hairball

Networks are usually drawn using a technique called node-link diagrams. While that works well for small graphs (the technical name for networks), it breaks down beyond a few dozen nodes. […] For a while now, people in visualization have talked about the graph without the graph, i.e., graph visualization without the hairballs. Networks are clearly important and challenging data, and it seems a bit myopic to only look at node-link visualization. Node quilts and the PivotGraph represent promising steps into a very different direction.

These are some good answers to how to scale graph visualizations.

Visualizing Hadoop data with Tableau Software and Cloudera Connector for Tableau

Put together one of the most impressive visualization tools, Tableau Software, with one of the best solutions for big data, Hadoop, and you’ll probably get some astonishing results.

Cloudera Connector for Tableau

Credit Cloudera.

While Tableau Software works with structured data only, with this connector it gets access to Hive through HiveQL.

Reddish: A Visual Admin and Data Analysis Tool for Redis

The initial feature set of reddish, a quite stylish[1] new Redis admin tool, created by Jim and Danielle from FreeFlow Labs:

  • Support for redis data structures
  • Pretty JSON formatting
  • Built on node.js
  • GUI commands labeled with their CLI counterpart
  • Command-line replacement with inline helpers
  • Real time updates. Who wants to keep refreshing the page or hitting a button/keystroke just to see changes?

There’s one thing I don’t understand though: reddish hosted model. Hosted monitoring services are OK. But a hosted admin tool doesn’t sound right.


  1. Based on the 3 screenshots shared in the post. I’d really appreciate an invite though.

Tableau Software: The Good, the Tech, and the Bad

The good:

Christian Chabot[1]: “Every instance of people turning raw data into something useful includes turning it into a picture”

The tech:

VizQL, the visualization query language that powers the software, was developed at Stanford University by Chris Stolte and Pat Hanrahan, a founding employee at Pixar and the chief architect of that company’s RenderMan visualization and 3D rendering software—an effort that won him two Oscars.

The bad:

Unlike many emerging data technologies, Tableau was built for structured data—whatever fits nicely into rows and columns […]

As a final note, Tableau is able to draw some of the most beautiful graphics I’ve seen. They are much nicer even than Horace Dediu’s graphics.
