Visualising the value of the NBN - calculated with Observable

01 May 2018

A University of Melbourne training on Interactive Data Visualisation was held on 17,19 April, 2018.

Observable is a remarkable tool that combines, html control elements, plot.ly data visualisation and javascript calculations to produce interactive, attractive and reactive calculations and visualisations. See my Observable NBN model here.

See an interesting Observable model of a spinning globe and another(using D3).
See my simpler version here:

Documenting the Observable Model

A 5 page explanation of the model is available at Figshare: https://doi.org/10.6084/m9.figshare.6030926

Calculating the value of the NBN

I used Observable to make a dynamic, interactive model to calculate the value of NBN. I used html sliders to control various assumptions, such as mobile vs fixed broadband use, % of gigabit users, % debt repaid per year.
