Creating a Thematic Map

In this tutorial, we are going to explore some of the datasets within AURIN that deal with health data. To begin, we will create a Choropleth map illustrating the incidence of Type 2 diabetes across SA2s within  the Greater Metro Melbourne area. Navigate to a state of your choice:

[Select your area > Australia > States and Territories > Victoria > Greater Capital City Statistical Area > Greater Melbourne]

Next, select the dataset attributes indicated in the figure below:

Once you have added the dataset, you need to load it, that is, retrieve the specific data that you’re interested in from the source. To do this, click on the eye symbol next to the data entry in the Select your data panel.

Once this dataset is loaded, we want to create a choropleth of the state (detailed information on creating a choropleth map can be found here).

Bring up the attribute table of the dataset (again, by clicking on the eye symbol next to the data entry under Select your data) and sort by the column containing the rate of diabetes from highest to lowest. Now we can now mouse over the data to see the corresponding incidence of type 2 diabetes.

Now we want to look at the relationship between different types of diseases across Victoria. Firstly, remove the choropleth from your Visualise your data panel (by clicking on the spanner next to it and then selecting Remove). Next, remove the dataset from the Select your data panel – because we want to select a bunch of new attributes, we have to begin with the data selection again.

Next, add datasets as you did before (searching for the Chronic disease data), but rather than just type 2 diabetes, select some other health outcomes that might be of interest to you. Remember to select the version of the disease that represents the Rate per 100. For this example, we have included type 2 diabetes, as well as hypertensive disease and male mental health disorder. Once you have added the datasets, reload them (again, by clicking on the eye).

Next we want to create a scatterplot of type 2 diabetes against other diseases. For this we will use the interactive scatter plot, under the  Visualise your data panel. For the first of our two scatter plots, the parameters are entered as below. Once you have added the visualisation it will appear in your Visualise your data panel; by clicking the show/hide eye symbol, the scatterplot will appear.

One of our scatterplots should look like this:

Because the scatterplots are interactive, we can brush over the points and find where certain high values are on the map:
