R: Life Industry Stats in Tableau and R

R: Life Industry Stats in Tableau and R#

By Pat Reen - originally published on his GitHub site here, which has the original code.

Overview#

APRA release Australian life industry data on performance quarterly at a product level as well as aggregated results by company. Bi-annually APRA release other statistics on lapse rates, new business rates, decline rates and market share. This section presents a visualisation of these datasources in Tableau. Also included is an R script which could be used to extract results from the APRA data.

Tableau public is a free to use visualisation tool that can ingest data in a number of different formats and is useful at creating flexible visualisation.

See link above to GitHub repository which has data and tableau workbook for this recipe.

Introducing radial bar charts#

A radial bar chart is a bar chart plotted in polar co-ordinates rather than a Cartesian plane. This site sets out a very simple approach, which are used here.

The result#

A preview of the final visualisation is below (click through to Tableau):

Using r to view industry stats#

As with most data sources, an alternative visualisation tool is R. The below extracts the individual disability income profits and revenue and calculates the margin.
