In this video, we will be creating a Radial Bar Chart in Tableau. We will be using Data Densification and leveraging various Table Calculations in our bespoke data visualisation.

Now that we have downloaded the Tableau Extension API, we will go through the various folders, install the Tableau Extension API SDK Components, Build the TypeScript Samples, and test our extensions using a local server.

We will now add our second layer to our Sunburst which will complete our bespoke data visualisation from a functional point of view. Once we have our second layer, we can add additional layers through manipulating our data source.

Microsoft VS Code is a code editor refined and optimized for building and debugging modern web and cloud application. The best part, Microsoft VS Code is a free Integrated Development Environment (IDE) with an abundance of extensions.

Node.js is an open-source, cross-platform, JavaScript run time environment that executes JavaScript code outside of a browser. Node.js comes with the Node Package Manager (NPM) that helps us install the required software.

Check out the following tutorials for you to get through. Given you have come all this way and completed the course, you will be in a better place to understand how these bespoke data visualisations work, and hopefully, they will spark off your imagination.

In this lecture, we are going to look into the technique of Data Densification; this technique allows us to take two points and create additional points between for manipulation, so in essence, making our data more dense.

A lot of people look at visualizations and think that they can never build it, however, this could not be further from the truth. Once you see a data visualization, you can distil, sketch and design a bespoke visualisation that can be built in Tableau.

Using our prepared data source, we are going to draw our the first segments of our Sunburst chart so that we have a basic understanding of the mechanics. This is always the important first step as we will very quickly see if this is going to be fit for purpose.

An important first step is to set up your development environment. In this section, we have a series of videos to help guide you to install the required software and various packages (this is my decided set of tools). If you would prefer, you can download and work through the written installation guide attached in the resources.
