Creating a Tableau Dashboard

Hi, Good day.

I am planning to develop a tableau dashboard. My KPIs with metrics related to Global Climate, Birth & Death rates. Please refer to the below for additional information.

* Global Climate & Environment
- Air Quality for the past 5 Years
- Air Quality Before Covid & After Covid
- Pollution for the past 5 Years
- Pollution Before Covid & After Covid

* Global Birth & Death Rate
- Birth Rate Count & percentage
- Death Rate Count & percentage
- Birth Rate Before & After Covid
- Death Rate Before & After Covid

I need a clean and simple dashboard, not so many charts and information. Please see the attachments for some model dashboards I like.
Charts: You can choose suitable charts based on the KPIs. I would also recommend some graphs as per my thoughts.
Please write me for further questions.
