In this lecture, we are going to look into the drawing curved lines using the SIN() Function. We will use Data Densification, Table Calculations and the SIN() function to draw this data visualisation. This lecture will help cement our knowledge on the techniques presented.

We will talk about the nature of bespoke data visualisations, what they are, and how we can achieve these in Tableau.

Prettier is an opinionated code formatter. It enforces a consistent style by parsing your code and re-printing it with its own rules that take the maximum line length into account, wrapping code when necessary. This will help keep our code looking nice and save the tedious work of formatting.

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.

There is some contention and disagreements about the use of bespoke data visualisations, and we will discuss the pros and cons of bespoke data visualisations, when to use them, and more importantly, when not to use them.

We are going to complete our first layer of our Sunburst using additional Table Calculations to position our segments around the circle. We will need to move our segments around and make sure they are relative to each other.

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

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.

That must have felt like a mini marathon, but alas we are done and will now do a review of the end-to-end design, data preparation, and build of our Sunburst Bespoke Data Visualisation.
