All right, very good!
Let’s take a look at the following picture.
This is where we want to get by the end of
our exercise.
Our goal is to create a dashboard containing
three charts.
A chart showing us the number of reviews with
a second axis measuring the monthly average
score.
Then we would like to create a pie chart showing
us the percentage of reviews each audiobook
obtained (for example 50% Audiobook 1, 25%
Audiobook 2, 10% Audiobook 3, and so on …).
And finally, we would like to create a chart
that gives us information about the ratio
between reviews left and the number of audiobook
purchases.
Such a visualization would help us understand
what portion of people buying an audiobook
listen to it, and then leave a review.
Ok.
These three charts will be the foundation
of the dashboard we will create later on.
And, I’ve added a note on the side, showing
us that once the dashboard is ready, we will
be able to look at the aggregate data or use
a filter to monitor the performance of individual
audiobooks.
Sounds exciting, right?
As a side note here I would like to add that
in general, it is a good practice to sit down
and design your dashboards before you start
working in Tableau.
This allows you to have a pre-defined idea
of what you would like to achieve and to check
whether you were able to do that at the end.
Moreover, and what is probably most important,
this allows you to think what visualizations
make sense from a business perspective.
Ok.
Great!
Let’s get right into it in our next lesson.
