Presentation of hypothetical Use Case
- Summary
The purpose of this project is to build a highly interactive, self-service dashboard that gives users the freedom to easily explore the data without the need of requesting new reports or making changes to the dashboard that would require a developer.
- Challenges
The data does not seem to include sales numbers for every game published, but only top sellers. It also has some years missing, like 2015.
Despite the incompleteness of the data, we can still gather some interesting insights just by exploring the data with the dashboard.
- Data Preparation
The data includes sales amounts divided by regions with a separate column for each region. This makes it impossible to visualize the data as a stacked bar graph with each region presented as a different colored stack.
To solve this I had to put all the sales data into a single column and add a column for the region. This was easily done in Tableau and Google Sheets. I isolated each region’s sales in different google sheet tabs and then performed a Union in Tableau to add them all to a single dataset.
- Results
I have prepared a slide presentation that shows a hypothetical use for this dashboard. The link to the presentation can be found on the left side of this page.
