Flu Trends | How We've found that certain search terms are good indicators of flu activity. Google Flu Trends uses aggregated Google search data to estimate current flu activity around the world in near real-time. Each week, millions of users around the world search for health information online. As you might expect, there are more flu-related searches during flu season, more allergy-related searches during allergy season, and more sunburn-related searches during the summer. We have found a close relationship between how many people search for flu-related topics and how many people actually have flu symptoms. United States: Influenza-like illness (ILI) data provided publicly by the U.S. These graphs show historical query-based flu estimates for different countries and regions compared against official influenza surveillance data. So why bother with estimates from aggregated search queries? Early detection of a disease outbreak can reduce the number of people affected. Model Updates
Official google.org Blog Tableau Love: Archive Tableau Friction I’m now using #Tableau Public to manage my blog content! | 3danim8's Blog Introduction I think that writing a useful blog shouldn’t be too hard with the technologies we have. But it is. Not that writing about interesting topics is the primary challenge, but allowing others to find and use the information that you have written about is really hard to do. Figure 1 – My blog from today. I have come to realize that by their very nature, blogs are just one big list of serial topics over time. I have simply gotten tired of writing HTML links and tables, seeing mis-formatted tables and incorrect color renderings on different devices, and seeing garbled pages on this blog. The solution to the problem! The solution is called Tableau. Figure 2 – The Tableau-powered dashboard showing the content of 3danim8′s blog (click to go to live dashboard!).

Fonseca Data Science | Leigh Fonseca's Explorations in Data Tableau Love As a “Friday afternoon fun project” I decided to tinker around a little bit with Tableau on Amazon Web Services EC2. Then bad Russell arrived in my head and kept on asking questions. A weekend later, I find that I’ve stood up and banged on about 20 distinct EC2 instance configurations. I installed Tableau Desktop & Server to each one and compared what I saw. I’m tired but vaguely satisfied. God knows what my bill from Amazon will be. In this two-parter, I’ll let you know what I found. The Goal Understand HOW Tableau behaves on EC2. Not the Goal Create prescriptive guidance on the instance type and storage subsystem you should stand up for various sizes of Tableau Server. What I did I decided that my “base” dashboard should be an interesting one. Viz One plots the trade price of a couple hundred equities across time (quarter) and trade sizeViz Two plots the trade price for two securities across time on a daily basis On my main workstation I see the following results: My Mac (jealous much?..
Jewel Loree » Pop Viz: America’s Regional Tastes December 17, 2013 When Allrecipes reached out to Tableau to create a dashboard about Thanksgiving recipe trends, I was salivating… not just because of all the appetizing recipes but because this is some deliciously juicy data! The Allrecipes data team (shout out to my man Bob, who is awesome!) provided me with data on page views for Thanksgiving recipes broken up by state (based on IP address) and category (turkey, stuffing, pie, etc.). It was a super fun viz to make and I learned some useful techniques via my own personal Tableau master and desk neighbor Dan Hom about the new 8.1 ranking feature. The Map Obviously, the main feature of this viz is the map. Write the calculations for Rank and for hiding everything but #1. The category selector I really like using icons as buttons for filters. I grabbed the icons from a set of food icons in Smashing Magazine. The Top Recipe box There are actually three sheets going into this section of the viz and an image. The Table That was pretty much it!
Understanding Table Calcs using Index() - The Information Lab I’ve been a Tableau user for two years now. Since joining The Information Lab a few weeks ago I decided it was about time I stopped being scared of table calculations and started understanding them more. One of the biggest hurdles of table calcs is understanding just what they are doing with your data and what the difference between using a Table (across), a Pane (across) or any of the other ‘compute using’ options is. How Tableau computes table calculations When we select a table calc, Tableau first queries our data source (whether that be a database connection, extract, or spreadsheet). The query then returns the data for the table calc in a temporary table stored in cache. Okay, so now we have a brief understanding of what Tableau is doing to create a table calc, let’s go ahead and connect to Superstore Sales in Tableau Desktop and start creating some table calcs. I’ve placed Year and Month of Order Date on the columns shelf, and Sum of Sales on rows. So, pretty straight forward here.
