Small Multiple Flows in Tableau

Small Multiple Flows in Tableau

Small Multiple Flows live up to their name, combining small multiples and flow elements in a single viz. This allows us to combine a set of events, providing an intense data visualization about these events, while also connecting one event to the next via the flow element. This technique does need a viewer to invest some time into understanding the various pieces of the visual. There is a lot going on, thus it will definitely require effort and a little time on the viewer’s part (and why I put detailed legends on both visualizations).

Comb the Hairball with BioFabric in Tableau by Chris DeMartini

Recently I posted about creating circular and hive plot network diagrams using Tableau and a question was posted around whether we could also execute theBioFabric network graph within Tableau. There is a lot of additional information about the BioFabric network graph at their website. The super-quick demo is a good intro to the graph if you have not seen it before.

The answer to the question posted is yes and this post is designed to walk you through the steps needed to build your own BioFabric graph within Tableau.

4th Grade Viz-tastic-ness

Last Friday, I had the pleasure of being a guest speaker in my 4th grader, Max's computer class, on the topic of Data Visualization.  They had just started to learn about creating spreadsheets in Excel, and so I used that as the basis for how to communicate effectively with data using Tableau. We started with a table of data in Excel, where we captured very basic data about Gender, Age, Birthday, Favorite Sports, Movies, Games, Foods, etc. and used this to discuss the following topics and build a dashboard all in 45 minutes!:

30 Minutes… Bay Area Bike Share

This is an entry for the Bay Area Bike Share data challenge sponsored by Stamen Design.  Allan Walker and I decided to examine the announcement of the expansion of SF bike station locations to new neighborhoods and see how that would affect the ability to use the service as a viable commuting option for different locations in the city.  Please visit the mapping methodology tab to understand the geo-spacial calculations Allan used to create the routes and service area visualizations data and information used to create the viz.

This Story Starts with an Irresistible Map

I wanted a Stamen style map in my Viz!  No problem actually, as I could easily design it and export it as an image.  Then I could just use it as background image in Tableau after assigning some Lat, Long coordinates to it.  Viz done… booyah!

Wait, I can't drill into the map and zoom and stuff?

Captains Log… Feb. 6th.  Love the look of my knock off from China town.  I think Shrimp Boy may have had a hand in it even, but I want a real pink pony...

Design Your Data Viz Like a Product Designer

Design Your Data Viz Like a Product Designer

After presenting on “Using Design and Emotion to create a Viz with Impact” at TCC13, one of the most common feedback comments was, “I never realized how many iterations and how much time you put into your viz’s.”  Having studied Industrial Design, it seemed only natural to follow a “Product Design” process when creating data visualizations.  Isn’t a data viz a product that you hope people will “consume” because they find it of use and of value? People are bombarded all day long with emails, tweets, Facebook posts, etc.  Why should they spend the time to look at your data visualization?   Just like a product, your viz should be designed with a specific goal and context in mind, and should capture the consumer’s attention immediately and provide a value to them.

SNAP back to reality

SNAP back to reality

This viz was inspired by Ron Shaich, founder and CEO of Panera Bread, who participated in a seven-day SNAP Challenge - living on a food and beverage budget of $4.50 a day, the average benefits available to a beneficiary of the Supplemental Nutrition Assistance Program (food stamps). "I had no clue. My SNAP Challenge last week taught me that merely observing someone else's plight does not hold a candle to consciously altering your habits to better understand what it might be like to live someone else's life." The CNN article on his experience can be seen here . This viz invites to you take the "SNAP challenge" as well as provide some information on the SNAP program from 1986 - 2012.

Using Design and Emotion to Create a Data Visualization with Impact

This is the slideshow from my session at the Tableau 2013 Customer Conference.  This session will walk through the process of creating a data visualization based on product design principles and ideas, focusing on overall product goals and user context. A step by step walk through of the design process for two data products, "Twitter TV Set" and "Firework Injuries" will be used as examples to highlight the impact that design and emotion can add to a visualization.

Firework Injuries

Using data from the Consumer Product Safety Commission, this visualization highlights all the injuries due to fireworks that happen, highlighting the 4th of July holiday period.  Click on any category to filter on it, and explore what injuries occur across dates, genders, and age groups.  Males seem to be more likely to get injured overall, and their injuries are to their hands and fingers.  Females, are more prone to head and neck injuries.  Sadly, wee ones are almost 10% of injuries, mostly over the 4th of July week.  Hover over any category and you can drill through to the gory details of the injuries (even the naughty bits). Please be safe this 4th of July and enjoy fireworks responsibly.

Federal Budget and Presidential Popularity

This viz was created before the 2012 Election to showcase Federal Budget deficits and surpluses, as well as the % of GDP the budget represented, over time.  An additional view of presidential popularity was also provided along the same timeline.  No correlation is implied.  It is interesting to now the extreme volatility of popularity as well as the limited number of Presidents who enjoyed an increase over time.  The viz provides insight as to the effects of historical events, such as wars and economic fluctuations may affect popularity.

The Great Divide

This viz was created based on the research of Thomas Piketty and Emmanuel Saez, "Income Inequality in the United States, 1913 - 1998". It shows the Income Share or Average income over time and by income group. It also provides an additional layer of user selected historical context data, such as GDP and CPI and the ability to change the "benchmark" year so changes relative to a specific time period such as wars, or deregulation can be highlighted. This viz was the winner of the Tableau 2012 Biz Viz contest.

Heatmap Checkout Abandonment Flow

This viz displays a visual walkthrough of the checkout process for a fictitious retailer. Rather then display a table or funnel of the data, this layout uses images of the checkout flow as background maps, shows visually where the abandonments occur. This allows the added insight of examining the UI along with the data adding richer insight into the flow.

Dynamic Report Templates

This presentation was created for the Tableau 2012 user conference Tips and Tricks session. It walks through how to create a dashboard "application" for users that may want to have a simplified way to create basic reports, dashboards or charts, such as for PowerPoint presentations. The output is highly formatted and presentation ready, shielding the user from having to do any formatting or branding. The concept uses the sample data from a fictitious coffee merchant. The user has the ability to select the report attribute being reported on, the metric uses to monitor performance, filter criteria and the output chart or dashboard display. Use the tabs to walk through the presentation as well as a step by step "how to". The concept is called the "Chart-o-Matic".
