Simple right? Data Visualization for the Web. Create: Information Wheel. The top 20 data visualisation tools. One of the most common questions I get asked is how to get started with data visualisations. Beyond following blogs, you need to practise – and to practise, you need to understand the tools available. In this article, I want to introduce you to 20 different tools for creating visualisations: from simple charts to complex graphs, maps and infographics. Almost everything here is available for free, and some you have probably installed already. Advertisement Entry-level tools At the entry level, we'll be looking at unexpected uses for familiar tools. Perceptual Edge’s 2012 Dashboard Design Competition.

A few weeks ago I mentioned in this blog that I would soon announce the 2012 Perceptual Edge Dashboard Design Competition.

Perceptual Edge’s 2012 Dashboard Design Competition

Today, the competition officially begins. This will be the most challenging event of this type to date resulting in the most esteemed award for dashboard design (in my not-so-humble opinion) since I judged a similar competition for the B-Eye-Network back in 2006. This competition will serve several purposes: A showcase for the current state of expert dashboard design.An opportunity for me to use the submissions to teach best practices by critiquing several of them on this website and in the second edition of the book Information Dashboard Design, which I am currently writing.An opportunity to provide sample dashboard designs that could actually be used to improve the quality of education in schools, for this competition involves the design of a dashboard that could be used by teachers to monitor the performance of their students. Here are the basic facts:

Five of the Guardian Datablog's best visualisations.

The aim of the Guardian when it comes to data is to guide the public through the mass of information available and present it in an attractive and easy-to-understand format. Speaking at the PPA (Professional Publishers Association) conference this week Rogers said: "What's happening is we're not just data analysers, we've become data providers. "What we’re doing is essentially journalism, but it’s different journalism. Try the VIDI Wizard: Build and Embed Visualizations. Why has Data Visualization Become so Popular? Not all that long ago, when someone mentioned data visualization images, graphics printed in the USA Today, New York Times or the Economist would instantly come to mind – not any more.

How to Pick a Chart for Your Dashboard. As Dashboard Spy readers know, dashboard chart selection is fraught with peril and the subject of many books and blogs.

How to Pick a Chart for Your Dashboard

I’ve written at length about the relative merits of different chart types and stress how the decision of which chart to use should not be made frivolously nor at random. To help you (or perhaps to confound you further), I present the “Chart Chooser” or aka “Chart Selections Thought Starter” from Take a look at this screengrab of the graphic and I’ll give you a higher resolution pdf link below the chart.

Infographic vs. Data Visualization (Who Cares?)

To the great dismay of art directors, designers, etc. these terms are even being used interchangeably. For clarification, I went digging around the Web and found a pretty great summation of the differences from Nick Iliinsky: “Infographics are the ones that are usually illustrated by a graphic designer; they’re probably done in Illustrator, there’s some data in them, but they’re not necessarily data-rich. They tend to be manually authored, manually constructed — obviously on a computer — but somebody sat down and said, “we’re going to put the big windmill here for ‘more windpower’ and more sunshine for ‘more solar power’ and a smaller oil barrel here” or whatever. R, Octave, and Python: A Follow-Up.

In my recent article posted on May 16, I compared functionalities for R, Octave and Python at a very high level.

Battle of the Charts: Why Cartesian Wins Against Radial. Undeniably, radial charts based on a polar coordinate system are more visually appealing than regular line, area and bar charts, or even tree maps, all of which are based on a cartesian coordinate system.

Battle of the Charts: Why Cartesian Wins Against Radial

Unfortunately, they are rarely better at communicating information. Radial charts are things like radar charts, Coxcomb charts, radial bar charts, or radial tree maps. These charts are all very visually interesting. The have relationships that our brain can easily detect, but that are hard for us to interpret. This duality is why they are more beautiful, but at the same time worse, for showing data. Visualizing Massive Amounts of Big Data. At the end of the day, the whole point of a business intelligence (BI) application is to make it easier to discern patterns and trends that would otherwise not be obvious.

As such, the competition between BI applications is ultimately going to come down to which one best fulfills that mission, especially in an era where Big Data is making massive amounts of information readily available. Pentaho upped its game in that regard with release today of version 4.5 of its namesake open source BI application, which enhances the application's core visualization engine with new geo-mapping, heat grids, scatter/bubble chart visualizations, interactive visual analysis capabilities such as lasso filtering, zoom and attribute highlighting on all chart types, and a variety of reporting enhancements. The good news is that rather than extrapolating insights based on a thin slice of data, NoSQL databases make it easier and more affordable to base decisions on large sets of complete data.

Interactive Dynamics for Visual Analysis. Graphics Jeffrey Heer, Stanford University Ben Shneiderman, University of Maryland, College Park The increasing scale and availability of digital data provides an extraordinary resource for informing public policy, scientific discovery, business strategy, and even our personal lives. To get the most out of such data, however, users must be able to make sense of it: to pursue questions, uncover patterns of interest, and identify (and potentially correct) errors. In concert with data-management systems and statistical algorithms, analysis requires contextualized human judgments regarding the domain-specific significance of the clusters, trends, and outliers discovered in data. The Miso Project. The Audacity of the Visually Inclined. Michael Dillon Scott has a very bold face. His eyes are deeply set, his brows are thick and rumpled, and the pronounced divot between his mouth and nose (I looked it up, it’s called a philtrum) gives off the impression that he is constantly on the verge of smiling.

As the author of over 100 books, including a recently completed series called The Secrets of the Immortal Nicholas Flamel, Scott attributes his prolific output to the use of visual processes (hence the details — it’s impossible to mention him without getting visual about it). The Visual Cue For starters, he takes pictures. Lots of pictures. Twitter analysis of air pollution in Beijing.
