Having worked with several BI software and tools for couple years ago, and mostly with Power BI from my recent job, I have seen data visualization technologies growing incredibly fast, and to my knowledge, Power BI and Tableau are the first and second most popular business intelligence tool on the market. To be honest, I haven't even tried Tableau either for my work or study, but now I finally took some time to try my hands on with this software, and it's actually two weeks creating a dashboard from scratch.
This is my very first Tableau viz and most of the learning went through online Tableau community forum and Youtube videos. To make it more simple and skip all the ETL steps, I reuse the NSW best school dataset from one of my projects. This dataset is very much clean and comprehensive. Below is what I have tried for this viz:
- Using Parameter and Calculated fields, together with Dashboard actions to swap visuals.
- Understanding of level of details (LOD) calculation in Tableau
- Utilizing the most basic charts for Dashboard visualization
- Customizing format for worksheet and the main dashboard
The viz can be found below and I welcome for any comment or feedback.
