Bottom line on Data Visualization

The market for data visualization software has bloomed. I'm suspicious.

Companies like Tableau, Spotfire, SAS Visual Analytics, Qlik and Zoomdata are positioning their tools far beyond traditional business intelligence.  Capabilities for graphically navigating data, recognizing patterns and finding relationships are growing in both functional and economic scope.  These new tools can provide charting forms only imagined in the last decade like word clouds, circular hierarchies, tree…

Dark Art of Warping



The celebrity of Toronto's mayor has certainly drawn a lot of attention to the city in recent years. Several candidates are now running for Rob Ford's job. Since the mayor is currently undergoing treatment for cancer, he decided to withhold his candidacy in the upcoming municipal election. Being a longtime resident of Toronto, and being aware of the city's wealth and poverty, I'm always interested in how these competing needs play out when it is time to vote.  Consider the interesting…

Startups Innovating Data Science Platforms

Hadoop: The Elephant In The Room

So what options are left for these companies? Until recently..not many. There are a few startups looking to change this.
