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.

YARN is a package manager that we will use to obtain our external libraries. Yarn caches every package it downloads so it never needs to download it again. It also parallelizes operations to maximize resource utilization so install times are faster than ever.

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 have now learned quite a lot and practice does make perfect. Please follow the links below and complete the various exercises to reinforce your knowledge and learned techniques.

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.

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.

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.

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

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 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.
