A short demo of Isochrone polygons from here.com API displayed with ipyleaflet. Inspired by Data Viz Today Podcast Episode 20 and presented as a lightning talk at the August 2018 meeting of Tripython.
The easiest way to run the demo is to use Anaconda for your operating system.
Create an environment for Python 3.6 with the required packages.
conda create -n isodemo python=3.6 arrow ipyleaflet requests tomlActivate the environment.
source activate isodemoTo run the UI version of the demo install ipywidgets and appmode
conda install -c conda-forge ipywidgets
conda install --channel conda-forge appmode Go to developer.here.com to sign up for an API key. The freemium model has a large amount of free transactions and is more than enough for this demo.
Clone this repository and create a file named credentials.toml with this format. Note: this is not a secure way to manage secrets in python, but is easy for a demo.
