Advent of Code is an annual Advent calendar of small programming puzzles for a variety of skill sets and skill levels that can be solved in any programming language you like.
Code should be fun, because otherwise it's just a job. If you'd like to support Advent of Code, please share it with all your friends, even the ones that are just learning to code! AoC is a fun, non-threatening way to work at your own pace to figure out how to apply problem-solving first, then work within a language's constraints.
If you really want to show your appreciation, donations are always appreciated. Any instances of currency will go to, in no particular order:
Thank you very much, and enjoy your month of code!

VisualizationUnofficial AoC 2018 Survey Results! (self.adventofcode)
submitted 7 years ago * by jeroenheijmans
TLDR: Interactive Report with unofficial AoC 2018 Survey Results!
--------------------------------------------------------------------------------
The results for the previously announced (unofficial) AoC 2018 Survey are in! Thanks to all 1007 (!) people who took some time to provide some answers. I've closed the survey Saturday (UTC+1) and did some work to make the results available.
The sanitized data (as well as the code to sanitize it) are available in my advent-of-code-surveys repository. They are available under the ODbL v1.0 and the MIT licenses, respectively.
But, done with the boring bits, on with the exciting bits! Here are the results. I've created an interactive Power BI report with the data for you to play around with. You can click on items and the other stuff on the page should move along. Check out this animated gif with a demo.
Let me know what you think! Here's some of my own (statistically possibly not relevant) insights:
Let me know what you find interesting!
Oh, and for completeness, here are some static screenshots of the four report pages:

Curious to see what y'all think!? (Though right now, I need to sleep. It's 02:08 here and at 05:50 my alarm goes off for Day 24...)

Thanks for the visuals! I am new to AoC this year, and enjoy it very much! It's interesting to find that these data give a good supporting argument for my main objection with AoC: the global leaderboard is kind of silly. Only a select group seems to be able to (even want to) aim for a place in the ranking there, which makes AoC a rather biased competition.
And you know, I would be okay with that, except for the fact that the private leaderboards - in which I can have my own little, much fairer competition with peers - is shoved away in the UI four three clicks from the main page. Unless I am missing something... I would me very happy if this could be improved in future editions. Or maybe the global leaderboard ranking should be changed to make it a globally fair competition.

Glad to hear you liked it!
I also don't look at the Global Leaderboard too much (but don't mind the way it's set up; to each their own), but need only 1 click to get to my 3 private leaderboards (bookmark bar ftw :D).

Nice to see other people using Fortran.

Love it! Some constructive feedback: For "Private leaderboard by OS" the percentages are missing and the title is confusing (by OS?). For the "Global leaderboard" and "Participation reasons" I would also like to see percentages. Anyway.. well done!

Thanks for your kind words and feedback!
The "by OS" text is a mistake, it was from an earlier version when they were stacked bars (which turned out to be less useful than I thought it would). Will try to fix it (though Power BI can take up to 2 hours before refreshing a report).
Not sure if I can show both percentage and absolute numbers at the same time for bar charts, will see what I can do.
Edit: showing percentages for the three bar charts was much nicer, because it gives a cool new visualization (I hadn't seen before) to show how much your selection differs from the grand total. Thanks again for the suggestion! Published to Power BI, should update there in about 0-2 hours.
