Thank you for checking out our Course on Creating Tableau Extensions.

In this lecture, we will be reinforcing our knowledge on our learned techniques to create a Packed Circle Chart in Tableau. We will be drawing circles and sizing them based on our data set.

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.

In this lecture, we will be looking at using Data Densification, Table Calculations and the Polygon Mark Type to draw shapes. We will combine all our techniques to draw a few fun shapes and will be building up to drawing more complex objects.

We will talk about the reasons for learning more about bespoke data visualisations and how, through learning about bespoke data visualisations, you will improve your Tableau dashboarding skills.

In this section, we are going to develop our first Tableau Extension, although, it will not do much for now, we will build our skeleton and make use of all the installed applications, tools and packages.

We are going to explore a Sunburst Chart. We will look at when could it be used, what use cases could it be appropriate for and, more importantly, when not to use it.

In this section, we are going to cover all the core Tableau techniques required to create Bespoke Data Visualizations.

Let us start by downloading the latest Tableau Extension API from the GitHub. Note that this course was built using version 1.3.0
