Welcome to the community, @lucas.sampaio! 
Are you looking to:
- Explore ECS with visualizations?
- Have a starting point for visualizing ECS data produced by some data source(s)?
- Other?
If no. 1, there's a past post that walks through the steps, including a link with an importable dashboard.
If no. 2, integration packages map to ECS and ship with visualizations/dashboards are good examples for a starting point: apache package
If other, share some additional detail about what you're trying to accomplish.
