[Project] Improve the accessibility of Bokeh's Gallery examples

[pavithraes]

Bokeh has an Examples Gallery with over a hundred example/demo visualizations. It is one of the most referenced pages in the Bokeh documentation. This project involves reviewing and updating ~30% of the example plots to be more accessible. It includes:

• Using the newly added accessibility colour palettes in the plots,
• Making sure corresponding documentation text has adequate context about the plots, and
• Creating some best-practices and guidelines for future examples to be more accessible.

Hi @pavithraes

While working on #7 I noticed there are no straightforward guides/examples in this section which makes using it kind of ambiguous. I think small examples can be added to this section on how to use the palettes from bokeh.palettes to make the guides better. What say? I can make a PR accordingly and update a few examples

Hello, @pavithraes I have a question. Are we only supposed to update the colors used in example gallery plots? For example how about adjusting the width, length, and scales used for some bars?
