Twitter published an awesome interactive data visualization Wednesday that shows what people were talking about during specific moments of President Barack Obama’s State of the Union Address Tuesday night.
You can see how people reacted to the speech in real-time by clicking the spikes on the chart to see which topics were tweeted about and what sections of the speech were talked about most. You can also break the chart down by topic and see what areas of the U.S. were tweeting most frequently. Interestingly, Illinois showed particularly high engagement on twitter during the paragraphs about cyber attacks and the proposal to make community college free for all students.
Check out the map and see how the U.S. responded on Twitter to the SOTU.
Overall, the rise of data journalism, the increase use of maps – good and bad ones -, and “storytelling” are among the most referenced topics in this list, but for a more comprehensive review of the year in data visualization, don’t miss the recent episodes of Data Sories and Tableau Wanna Be podcasts. Hope you enjoy the reading

I do not know whether this is a good news or not. R has been one of my favorite tools in BI and data analytics. I like the open source development environment of R. It has made R to be one of the most successful tool for both business and academy. Revolution Analytics has further enhanced the tool to support IDE, servers, and parallel processing. R has a lot of exciting progress in the past few years.
For Microsoft, it has been providing the 2nd best software in the past. Not until, it enhanced and focused on the development of its strongest product, SQL Server. It started to pay more attention to open source development these years and embrace it more than Oracle does. Examples include Codeplex, and free e-books, and on demand training to really open up its user market.
Microsoft indeed has been weak in Business Analytics, because its solution remains complicated and limited creativity. So, the business decision to buy Revolution Analytics makes sense to Microsoft. I just hope Revolution Analytics will be able to continue its research and development, and continue to support open source version of its products to benefit academic research.
A unique, huge study has found that when taxpayers help children in low income families live healthier lives those same children grow up to be more successful adults, thus paying more taxes that partly offset the cost to the government.
My recommendation is both.
