Add Option to Customize or Increase Font Size in Visualizations

[pascalbrunner]

Description:
It would be helpful to have a configuration option in OpenSearch Dashboards to adjust the font size for all visualizations globally or per visualization. While the current design works well for many, larger font sizes can improve accessibility and readability, especially for presentations or dashboards displayed on larger screens.

Proposed Solutions:
Provide a global setting in the dashboard's advanced options to define a default font size for all visualizations.
Add a "Font Size" configuration in the visualization editor for finer control over individual charts and graphs.
Workaround Tried:
I attempted to modify the CSS directly inside the running Docker container but couldn’t identify the appropriate paths or methods to target visualization fonts effectively. Guidance on modifying the relevant SCSS or CSS files would be appreciated if this feature isn't planned for implementation.

Benefits:
Improved accessibility for users with visual impairments.
Better presentation of dashboards in environments like meetings or large displays.
Additional Context:
I am running OpenSearch Dashboards in Docker. If CSS/SCSS changes can be achieved manually, documentation or guidance would be greatly appreciated.

@pascalbrunner When you say visualization font size, are your referring particular places? like x-axis, y-axis, legend or visualization title? Would be nice if you have a screenshot :)

Thank you for your answer.

Basically at several spots. Below the counter, the legends next to the pie charts and also the items in the list (as shown in the picture).
I run Opensearch Dashboard within a Docker. I would also be happy with the solution to modify some CSS on my own :)

I appreciate any help!
