This are the slides that I created for my talk at PyCon JP 2017. The talk was also recorded, and a video can be found here: https://www.youtube.com/watch?time_continue=3&v=Yd5oEIBFQ_E.
I made the presentation as a Jupyter notebook and Reveal.js, and I encourage you to head over to https://github.com/halfdanrump/geoviz-pyconjp2017, download the repository and open the presentation.ipynb notebook yourself.
The code that I presented in this talk is released as open source and can he found here: https://github.com/halfdanrump/geoviz
This work was done for DG Lab, the company that I currently work for.
