#SportsVizSunday Challenge Dec 2018

Dec 1, 2018

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.

As a guest host you are allowed to select the dataset. Since I am a sucker for winter sports in general and alpine skiing in specific and I love both, going skiing by myself and watching alpine skiing on TV, I was very happy when I discovered the large FIS (Fédération Internationale de Ski) database at fis-ski.com.

In this database you can find results of all disciplines organized by the FIS. Due to my love for alpine skiing I eventually focused on this discipline only (the database also includes cross-country skiing, ski jumping and other disciplines) and scraped the data for all races of the World Cup since it was established in 1967. The World Cup is a series of races in different competitions (Downhill, Super G, Giant-Slalom, Slalom, Combined/Alpine Combined) where the best racer of a season wins a so-called Crystal Globe, a small Crystal Globe for the winner of a competition (e. g. Slalom) and a big Crystal Globe for the overall winner.

Technical Challenges

• The results for the above-mentioned races include durations in seconds (for example the total race-time or differences between the racers within a race). In Tableau you can transform this duration in a date time with the following simple formula:
     datetime([*duration*]/86400)
  You can then change the date format in the default properties to a custom format
     hm:ss.00
  to display for example a duration of 105.23 seconds as a datetime like this: 01:45.23
  
• If you want to focus on specific athletes make sure that you include all data for this athlete because there might be little differences in the spelling of an athlete’s name.
• The disciplines Combined/Alpine Combined haven’t been included yet, therefore you can’t calculate the big Crystal Globe winner at this moment.
• You can find the data on data.world (Link) or you can use the below mentioned workbook that includes the same data.

Vizzing Challenge

The vizzing challenge is to create a visualization based on this dataset. It’s up to you if you want to focus on a certain athlete, a certain season, a certain competition or certain nations, like I did in a visualization on alpine skiing at the Paralympic Winter Games earlier this year.

For those unfamiliar with alpine skiing and the FIS World Cup I’ve prepared a workbook on Tableau Public, that can be used to explore the data and to find stories in it.

I hope you will enjoy this challenge. If you have any questions don’t hesitate to shoot me a message here in the comments section or on Twitter.

Please publish your visualization(s) on data.world and on Twitter including the hashtag #sportsvizsunday and tagging me (@ProfDrKSchulte), Simon Beaumont (@SimonBeaumont04), Spencer Baucke (@JSBaucke) and James Smith (@sportschord) to get feedback.

Happy vizzing!
