Online Courses

We will talk about the progressive nature of this course and introduce the various sections.

I will help you understand the basics of what is a Tableau Extensions. We will talk about the structure and architecture of an Extension, understand what Extensions are and how they are used, and more interestingly, how they are developed.

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.

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.

Google Chrome is a cross-platform web browser developed by Google. We will use Google Chrome to help debug and test our Tableau Extension.

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.

If you prefer following written instructions to set up your environment, this is for you. If you prefer video tutorials the rest of this section will cover your environment setup.

We have covered a lot of grounds and have learned some of the available core techniques that we require to build bespoke data visualisations. So let us review.

At this point we have installed various applications, tools and packages. In the next section, we will be putting this to work and developing our first Tableau Extension.

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.
