TOOLS, COURSES, AND EVENTS

A data visualization contest for $2,000 is being held by the Guardian in cooperation with Google and the Open Knowledge Foundation. To quote Simon Rogers: “All we want you to do is to take an open dataset from any government open data website […] and visualise it.” The contest is open to citizens of the US, UK, France, Germany, Spain, Netherlands, and Sweden.

If you need help picking optimally distinct color palettes for your contest entry, try iWantHue, a new app for data scientists. Choose your color space and your clustering method and watch an optimal palette gel together.

New to data visualization? Free online data training with an emphasis on visualization will soon be made available by the Knight Digital Media Center. These four workshops will be led live by Len De Groot. Registration opens February 18.

R users will want to learn about the 10 R packages that Yhat wish they knew about earlier. These packages will make it easier for you to work with strings, do time series analysis, and make random forest classifiers.

Statistical coders who love Python, meanwhile, will enjoy “Will it Python?”, a series of tutorials giving the author’s “attempts to port data analyses originally done in R”. It includes great examples for scikit-learn, Pandas, and more.

In other Python data science news, Hyperopt, a Python library for hyperparameter optimization—”for optimizing over awkward search spaces with real-valued, discrete, and conditional dimensions”—is now available via PyPi. Consult the wiki for details and documentation.

If you missed the Journalism Interactive 2013 talk “Data: Practical Tips from the Field” by Ken Schwencke, Sisi Wei, and Derek Willis, don’t worry: they’ve posted their slides online, including the presentation handout and links to examples.

In fact, if you missed Journalism Interactive 2013 altogether, maybe you should check out Dan Dreimold’s “somewhat live” blog post covering the conference, consisting of 100 things Dan learned (and you can learn too).

Clever°Franke’s social media sentiment map is a beautiful infographic tracing the relationship between Netherlands mereological data and social media sentiments about the weather. Its overall message: “The Dutch generally don’t deceive themselves about meteorological circumstances.”

Read an interesting conversation with dataviz experts Scott Murray, Rachel Binx, Mike Bostock, and Tom Carden from the Source. For another interesting interview with a data visualizer, check out this interview with Benjamin Wiederkehr of datavisualization.ch.
