Kids can help #VisualizeNoMalaria!

Hi, my name is Max. I am eleven years old and I am going into sixth grade.  I LOVE video games and Legos. Yesterday, though instead of playing Minecraft, I volunteered by tracing buildings with my Mom, to help support the fight against Malaria in Zambia.  

I did this because I like to be in the wilderness and go camping and have been bitten by mosquitos many times.  I can’t imagine getting sick or dying from just being bitten by a mosquito and don’t think any kid should worry or suffer from this.

It is really easy to help.  If you want to help too, go this link http://www.tableau.com/about/blog/2016/7/help-visualizenomalaria-56784  and follow the instructions.

The New Fabulous Mapbox Studio Tutorial - Making a more Accessible Map

Here is an example of how beautiful your new maps can be.  This one was designed to be a background map that was elegant and provided an alternate to just the black, white, and that other one that no one uses, that come pre-designed in Tableau.   Check it out live and zoom in and out.  Notice the color gradations as you zoom in close.  Those would have taken forever to get right in Classic, not to mention how amazingly smooth it is to zoom in and out and pan around.  This is a map Ferrari!

Easy Peasy Lemon Squeezy Mapbox Maps and Layers in Tableau 9.2

One of the features that I am most excited about in 9.2 is the ability to add Mapbox map layers from the UI in Tableau instead of having to deal with all the .tms hackery!  If you are a beta tester for 9.2 and are publishing to Tableau Public, this is already available to you to use!  Ready to check out how easy it is now?  I’m going to use my Skyfall themed map to show off how easy it is to add multiple layers, and then we will create a “bog normal view swapper” (a very technical term that Allan Walker seems to use a lot).This will allow the user to change the maps and layers in the background of your published workbook.

Fast and Fabulous Custom Maps using Mapbox in Tableau

So the last time I wanted a custom map, I ended up building my own WMS and spending months and $’s to get the map I wanted.  If you followed that advice - good for you. You and I can now drink at at Tableau conference and tell the young’ins about how we used to have to walk uphill in the snow, wearing only flip flops and a Magnum BI t-shirt, while being pelted with popsicles to get our maps. Then one day recently, I had a cocktail with Allan Walker (that insane mapping Zen dude) who pointed out that if you just opened up a .tms file in notepad, there just wasn’t all that much to it but a wee bit of xml.

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.
