Devil's tooltip (ubertip) in Tableau

The official name of this tooltip's the ubertip, but the devil's tooltip shows its real nature.

Ubertips appear after clicking on row or column headers, when clicking on a mark or data item in the view, they don't appear.

Simplifying shapefiles in MapShaper

Maps should be simple, simple to make and simple to use.

I simplify shape files to use them in Tableau but you can use them in other apps too.

Why should you do this?

Speaking in simple words Tableau draws maps by joining nodes with lines in order given by ShapeToTab. If there are many nodes Tableau has to work harder and performs slower. Besides that it is a great way of spending free time :)

Here you can learn what simplifying geometries of shape files is.

Arithmeum, part 1

I am planning to add a few posts about data in the real world, yes life and data also exist outside the internet. I have no idea how I will achieve this as I do not go out so often. Keep your fingers crossed :)

After reading this magical blog post you will appreciate modern data programs. You will purr like a kitty thinking of calculating on your computer.

I have visited Arithmeum, a museum devoted to calculating methods and machines. It is placed in Bonn, Germany
