Wolfram mathematica: data visualization example
This is example of visualization using Wolfram Mathematica, a commercial software package. We’ve previously discussed some of Wolfram’s other products and ideas in an earlier post on digital physics and cosmology as well as in our posts on IBM Watson. One of the reasons that data visualization remains something of a black art is that there are so many data visualization packages out there. Each package has its strength in a few kinds of plots or types of visualizations. Some of the better packages are commercial (and, unfortunately, not necessarily inexpensive). The high prices mean the experience of any practitioner is likely to be limited to a few commercial visualization packages over the course of a career (since most sites will only license a few packages). Open source data visualization packages are therefore very powerful, since they potentially combine the best of free tools. There are very good free tools out there.… Read the restMulticolor 3D scatterplot: traditional data visualization
Traditional data visualization: this is a multicolor scatterplot done at LLNL (Lawrence Livermore National Labs) near Berkeley, CA using the free, open source software package they developed (VisIT). VisIt can perform various transformations to attempt to visualize multi-dimensional data, including phase-space renderings and applying glyphs to show higher dimensions. The 3D scatterplot visualization here seems to be a more traditional 3D scatterplot, with color used to visualize a fourth dimension of data. (There are visualization techniques to attempt to show more than four dimensions, although your results may vary. Our earlier post showing a streamgraph shows one of these methods, although there are more. Conveying complex information in a meaningful way using tools like a multicolor 3D scatterplot is as much art as science, as you can see.)

Moving on from dashboards & scoreboards, let’s look at some cool data visualizations. This is a 2005 visualization of the Internet IP addresses — or an Internet map. It’s an example of data visualization for a network. Each line joins two IP addresses, with the length representing the delay between them. Less than 30% of reachable addresses were used to construct the Internet map, so this Internet map is only a partial map of the Internet at that time.
