In order to run the presentation, once you have downloaded or performed a git clone of the source code, open the index.html file in the browser.
The presentation itself works by pressing the left/right arrow keys in order to switch slides. This controls a JavaScript switch statement that defines what to do on each slide.
The core JavaScript file that runs the presentation is the functions.js file.
Some of the visualisations, for example the CICS Network chart at the end of the slides, have their code stored in a separate JavaScript file, which is imported into index.html, and consequently exposes it's functions globally. This means that we can call functions like NetworkChart() from inside functions.js
