How to become a data visualization ninja with 3 free tools for non-programmers
We noticed many times between the lines of this blog how data visualization is in the hype and how this trend is growing and growing. That’s good news guys! It’s fun and it’s … success! But as more and more people join this wild bunch we have to take care of those who are not as skilled as we are yet. There are many people out there who love data visualization but they think they are out of this business because they are not able to code. As data visualization develops we can expect to have people developing tools that are more accessible and easier to use also for non-programmers. By the way, if you are one of those wannabe non-programmer-data-enthusiast I have a good news for you: the future is here! Data Visualization is 80% data 20% visualization I don’t think I will find anyone arguing against this sentence. And there is also a subtler issue here. So here it is. The Ninja’s Toolbox Outwit Hub (data scraping) Outwit Hub is a little and fantastic FireFox add-on. Isn’t it fantastic?

Stephen commented in his OLDaily: And the good point he make is that the effectiveness (if you want to call it that) of a learning event isn’t measurable at the time of the event – you have to wait for the cycles to complete. Can the effectiveness of professional development be measured? I have composed a post on Teacher Training and classroom teaching here. I think an objective measurement of the effectiveness of professional development needs to be based on the context of application of the skills learnt and the teaching or learning situations. Besides, the sole reliance of professional development is often not enough, especially in a complex learning environment. What needs to be considered in mind could be illustrated with the pictures below: How about this?

Khan Academy 37 Data-ish Blogs You might not know it, but there are actually a ton of data and visualization blogs out there. I'm a bit of a feed addict subscribing to just about anything with a chart or a mention of statistics on it (and naturally have to do some feed-cleaning every now and then). In a follow up to my short list last year, here are the data-ish blogs, some old and some new, that continue to post interesting stuff. Data and Statistics By the Numbers - Column from The New York Times visual Op-ed columnist, Charles Blow, who also used to be NYT's graphics director.Data Mining - Matthew Hurst, scientist at Microsoft's MSN, also the co-creator of BlogPulse.Statistical Modeling - We might disagree on certain things, but Andrew's blog is one of the few active pure statistics blogs.The Numbers Guy - Data-minded reporting from Carl Bialik of the Wall Street Journal.Basketball Geek - Like statistical analysis and basketball?

The Role of Algorithms in Data Visualization It’s somewhat surprising to me to notice how little we discuss about the more technical side of data visualization. I use to say that visualization is something that “happens in your head” to emphasize the role of perception and cognition and to explain why it is so hard to evaluate visualization. Yet, visualization happens a lot in the computer also, and what happens there can be extremely fascinating too. So, today I want to talk about algorithms in visualization. What’s the use of algorithms in visualization? When do we need them? I have grouped algorithms in four broad classes. Spatial Layout. (Interactive) Data Abstraction. Smart Encoding. Quality Measures. These are the four classes of algorithms I have currently identified in visualization. Take care.

Visualization-based data discovery tools Visualization-based data discovery tools may account for less than 5 % of the Business Intelligence (BI) Market, but they are fighting above their weight in terms of profile. In 2011, Gartner placed Visualisation at the peak of the BI Hype Cycle. Despite this indicating the category may lose some of its lustre , Gartner are still predicting a compound annual growth rate of 30% in each of next 5 years. If true, this means the category will increase in value from $427 to $1,606 million over the period, a growth rate 3 times that of the overall BI market. So what are Data Visualisation tools and how are they defined? According to Gartner, there are 3 common elements Who are the main vendors in the Data Visualisation category? Gartner ranked the leading players, based on estimated revenue, to be Figure 2. With the expected growth of this category, large traditional BI vendors like Microsoft are scrambling for market share. So why the growth and hype in the Category? Rapid prototyping.

Time Zones Strategy Bank The Teach 21 Strategy Bank is designed to be a dynamic resource for educators.
