Right-click the pie chart

Select the best options for the data labels
Add patterns to a pie chart
Patterns are more accessible to a wider array of people with disabilities. Instead of relying on color alone (which is an accessibility failure) – use a pattern and a color.
Right-click the Pie Chart
Select Format Data Series
Choose the appropriate pattern and color
Add alternate text
Right-click the entire chart object
Select alternate text
Enter a detailed alternate text
Do you plan on converting the PowerPoint to another file type like PDF?
You might consider inserting the Pie Chart as a flattened image and providing alternate text instead. Screen readers can have difficulty reading the contents of a pie chart within the PPT itself.

How to apply slide titles in PowerPoint Video Overview
Why should I have unique slide titles?
People who rely on assistive technology to review presentations will often navigate by the heading or title structure. If you end up converting the document to another format like PDF, the slide titles will come through as headings.
In the example below there are 5 different slides that share the exact same title.
In order to apply unique slide titles simply add a number to the end of each slide. The quickest method to change the title of a slide is to edit in outline view.
Select Outline View
Then simply add a number or change the title altogether. The image below shows an outline view of a presentation with numbers added to make slide titles independent.
Content should appear in the outline view. Sometimes using textboxes can interfere with accessibility, so only use them if they are a part of your accessible slide design theme.
Outline view and textboxes in PowerPoint Video Walkthrough
In order for content to be the most accessible to people who use screen readers it is recommended that all content appears in the outline view of PowerPoint. The outline view shows a text-based version of the content with your file.
Additionally, the outline view offers a snapshot of all of the major content types in your presentation. It is an excellent method for organizing and chunking your information. It is also a great way to create a quickly accessible version for people with disabilities!
To view the outline view
Select Outline view
Review titles and content to ensure all content from slide is located in outline view
Avoid using added text boxes
The textbox feature will allow you to add extra content to a slide but it might not be accessible and it will not appear in Outline View properly. Additionally, it will cause extra problems when adjusting the reading and arrange order.
How do I ensure my content is in outline view?
This is purely based on using a theme and a slide template.
On the home ribbon, select Layout
Select the template you would like use
The last step of this process is to actually use the content boxes to place your content. Do not add additional text boxes in this step. Simply click into one of the content boxes to add the desired information. Using a template will not only add all content to the outline view, but it will also be in the correct reading order!
Edit the slide master theme in order to develop custom templates and ensure all the content is in order and available in the outline view.
