For this week’s #makeovermonday challenge I created this visualization combining a hex map and a panel chart (click to play with the interactive version on Tableau Public):
Ludovic Tavernier and I have spent quite some time on our collaboration project about the rise of tennis legend Boris Becker. One key element of our viz is something that we have called ‘bump trees‘, a two-layer chart that is combining (horizontal) tournament trees in the first layer with (vertical) bump lines to connect the different tournament trees of a player in the second layer (click the image to play with the interactive version and to read our entire data essay on Tableau Public).

When Simon, Spencer and James asked me earlier this year if I could join the #sportsvizsunday team as a guest host for one of the upcoming months I was very honored, and my answer was of course ‘yes’. I have followed this initiative since it was established, and it has always been fun to work with datasets on various sports in or beside the monthly challenges throughout the year. I have always used these challenges as opportunities to learn new techniques and chart types.
Scoring-Models are something like a Swiss Army Knife in decision-making and you can use them on almost unlimited occasions. They are models in which various criteria are weighted and result in a score. Based on this score a conclusion or a decision can be made or an advice can be given.
They follow a very structured setup:
- Define criteria
- Weight criteria
- Assess alternatives based on the defined criteria (e. g. on a scale from 1-10)
- Calculate part-scores ( 2. x 3. )
- Calculate overall score ( ∑ 4. )
For this week’s #workoutwednesday challenge I recreated a viz by Rody Zakovich (click to play with the interactive version on Tableau Public).
When I did this week’s #workoutwednesday challenge, I learned how to use the Index-Formula to filter measures within a view to create the BANs in my viz (click the image to play with the interactive version on Tableau Public). Probably not too spectacular to many of you.
Last week I wrote about how to create bounding boxes in Tableau. In my most recent visualization I used them to create a custom zoom control for multiple maps. Click the dashboard to play with the interactive version on Tableau Public.
For #makeovermonday week 34 I created a viz that is showing fatalities of crisis in Africa and Asia (click the image).
Some weeks ago this Tweet by Rody Zakovich caught my eyes:
