2022: Week 22 - Dungeons & Dragons: Critical Role

Challenge by: Will Sutton

We're starting June with a collaboration with #GamesNightViz and #DataFamCon: a monthly challenge with topics covering a wide range of the geeky world including TV Series, films, books, and even some data about geek culture and conventions itself. 

For this challenge, we'll be looking at a Dungeons and Dragons dataset from the podcast "Critical Role". If we wanted to know how long each character speaks for during each episode we'd need to do a little bit of preppin' to prepare the dataset for such an analysis. 

There's an additional bonus challenge to build the following dashboard using the data we'll prep. Find the details at the bottom of this post!
Find the viz designed by the super talented Christina Gorga here

Inputs

  1. Episode Details 

  2. Dialogue 

Requirements

  • Input the data
  • To create our gantt chart we'll need to work out how long each character is talking. To do this we can work out the difference from one timestamp to the next. However for the last lines of dialogue we'll need to know when the episode ends. To do this we'll need to union the dialogue with the episode details to find the last timestamp
  • Create a rank of the timestamp for each episode, ordered by earliest timestamp
    • Think carefully about the type of rank you want to use
  • Create a new column that is -1 the rank, so we can lookup the next line
  • Create a duplicate dataset and remove all columns except
    • episode
    • next_line
    • time_in_secs
  • Inner join these two datasets
  • Calculate the dialogue durations
  • Some character names are comma separated, split these names out and trim any trailing whitespace
    • It's ok to leave "ALL" as "ALL"
  • Reshape the data so we have a row per character
  • Filter the data for just Gameplay sections
  • Ensure no duplication of rows has occurred
  • Output the data

Output

  • 7 fields
    • Episode
    • name
    • start_time
    • Duration
    • youtube_timestamp
    • dialogue
    • section
  • 270,809 rows (270,810 including headers)
You can download the full output here. 

After you finish the challenge make sure to fill in the participation tracker, then share your solution on Twitter using #PreppinData, #GamesNightViz and #DataFamCon and tagging @Datajedininja, @JennyMartinDS14 & @TomProwse1, @WJSutton12, @StyleSTEAMed & @NicoleKlassen12

You can also post your solution on the Tableau Forum where we have a Preppin' Data community page. Post your solutions and ask questions if you need any help! 

Bonus Challenge

Now we've prepped the data, we can build a Gantt chart.

 

You can build a Gantt in a few steps:

  • Load the data in Tableau
  • Add "Start Time" to Columns
  • Add "Name" to Rows
  • Add "Duration" to Size
  • Next are some design choices for your viz
    • There are several episodes to choose from, you may want to give your user a filter to pick an episode or share your favourite episode
    • How would you like to share the character dialogue with your readers? Christina has used tooltips to share this data
    • All the dialogue comes with YouTube timestamps - you could add these as URL actions
Share your viz with your submission and tag #DataFamCon @StyleSTEAMed & @NicoleKlassen12

(You can add the #GamesNightViz crew but I’m aware there will be a lot of tags going on! #GamesNightViz @Visual_Endgame, @ninjavizlouis & @WJSutton12)

2023: Week 1 The Data Source Bank

Image
 Created by: Carl Allchin Welcome to a New Year of Preppin' Data. These are weekly exercises to help you learn and develop data preparation skills. We publish the challenges on a Wednesday and share a solution the following Tuesday. You can take the challenges whenever you want and we love to see your solutions. With data preparation, there is never just one way to complete the tasks so sharing your solutions will help others learn too. Share on Twitter, LinkedIn, the Tableau Forums or wherever you want to too. Tag Jenny Martin, Tom Prowse or myself or just use the #PreppinData to share your solutions.  The challenges are designed for learning Tableau Prep but we have a broad community who complete the challenges in R, Python, SQL, DBT, EasyMorph and many other tools. We love seeing people learn new tools so feel free to use whatever tools you want to complete the challenges.  A New Year means we start afresh so January's challenges will be focused on beginners. We will use dif

2023: Week 2 - International Bank Account Numbers

Image
Challenge By: Jenny Martin For week 2 of our beginner month, Data Source Bank has a requirement to construct International Bank Account Numbers (IBANs), even for Transactions taking place in the UK. We have all the information in separate fields, we just need to put it altogether in the following order: Inputs A list of the transactions, with information about the receiving bank account  A lookup table for the SWIFT Bank Codes  Requirements Input the data In the Transactions table, there is a Sort Code field which contains dashes. We need to remove these so just have a 6 digit string ( hint ) Use the SWIFT Bank Code lookup table to bring in additional information about the SWIFT code and Check Digits of the receiving bank account ( hint ) Add a field for the Country Code ( hint ) Hint: all these transactions take place in the UK so the Country Code should be GB Create the IBAN as above ( hint ) Hint: watch out for trying to combine sting fields with numeric fields - check data types Re

How to...Handle Free Text

Image
Free isn't always a good thing. In data, Free text is the example to state when proving that statements correct. However, lots of benefit can be gained from understanding data that has been entered in Free Text fields. What do we mean by Free Text? Free Text is the string based data that comes from allowing people to type answers in to systems and forms. The resulting data is normally stored within one column, with one answer per cell. As Free Text means the answer could be anything, this is what you get - absolutely anything. From expletives to slang, the words you will find in the data may be a challenge to interpret but the text is the closest way to collect the voice of your customer / employee. The Free Text field is likely to contain long, rambling sentences that can simply be analysed. If you count these fields, you are likely to have one of each entry each. Therefore, simply counting the entries will not provide anything meaningful to your analysis. The value is in
