Time sure flies.

It has been a while since I have posted a tutorial, but I think I have a good one. The idea of 3d representations for population data has been around for some years, but I wanted to look exclusively at the winning votes after all other votes have been cancelled out.

This post is going to be a little different from my usual, as it relies heavily on calls to ffmpeg. This should work on Linux/OSX just fine, but the system call will need to be modified for Windows.

This tutorial will mainly focus on ggplot and bigrams, but it does gloss over clustering for a heatmap.

This tutorial will cover exploring and visualizing data through 2018 for the Minneapolis, MN bike sharing service NiceRide. Part of what makes R incredible is the number of great packages. Part of what makes packages like ggmap and gganimate great is how they build on existing packages.

This is going to be a bit longer than some of my previous tutorials as it covers a walkthrough for sourcing data, scraping tables, cleaning, and generating the 3D view below which you can springboard from with the help of the rgl package. The heavy lifting is done with ggplot and rayshader.

If anyone else is like me, eventually when looking up a future destination you will stumble across the climate data table on Wikipedia. There is a lot of great information, but if you are planning a trip you might just want to see at a glance the temperature ranges for the months you are interested in traveling.

This script should help you scrape tables from Wikipedia
