Do you think Google will use chart extensions designed by experts
There are experts on the subject and there are experts in chart creation, and ideally the extension would include both types of experts. To add plugins to the schema, there is a page on Schema.org specifically about plugins.

There are experts who write in their fields. Here is an example of an add on about the science of the financial business industry. Here is another example from GS1 , the organization that brought barcodes to brick and mortar stores. If you run an e-commerce site, it is recommended to visit the GS1 demo.
SEO FAQ: When should I not use Schema
Schema Schema is an opportunity to present information from your site in a machine-readable way, like using an XML sitemap on your site is an alternative to an HTML sitemap.
Just as the information from an HTML sitemap and an XML sitemap should be consistent, the vocabulary of the schema and the HTML you use on the page should also be consistent.
Using the schema allows the site owner to describe the site's content in ways that may be meaningful to a search engine, using data definitions that have been agreed upon by subject matter experts who have worked on the vocabulary of a particular schema that may be appropriate for your site and the content it contains.
Presenting the content your pages cover in this way adds subtlety to your pages in a way that can give search engines a greater understanding of what your page is about, making it more likely that the search engine will bring people interested in the entities and concepts you write about on your pages.
The chart in this example is about Hyde Park, and it provides a URL for more information about Hyde Park that helps the search engine determine the exact entity the page is about.
SEO Questions and Answers
Question: The schema properties that we can directly observe in SERPs are still very limited, relative to the amount of theoretically relevant vocabulary that exists.
How deep is it worth going for most websites after the few most commonly used properties
And how can we demonstrate the value of depth beyond just what is reflected in rich snippets
We have to keep in mind that the scheme is still in its infancy, and Google is just starting to use it, but it's something Google has been working on since at least 1999, when it developed the DIPRE algorithm.
Google Maps is based on a patent on structured data, and it looks similar in many ways to organic search. The structured data that the schema brings us adds another channel of information that can be much more precise in terms of how it uses structured data across the web, and it adds an accuracy that allows for things like rich results.
If Google can create a rich and useful application, such as Google Maps, and the navigation that it brings us, it may be able to build on many aspects of using the scheme. It's likely to be used in places like:
Google Lens
Enable search by image, which uses the schema to find information about entities that can be searched in images.
Search based on location.
If Google knows what location you're doing a search at, it can answer questions about that location, such as businesses that might be nearby, points of interest nearby, events that might happen in the area, and jobs that might be offered close to the location.
Search based on properties of entities
Google has shown that it can answer questions based on the properties of entities. Including "properties" on your site helps make your website the user in search results.

. See device identifiers in Google Trends. If we can tag the entities that appear on our sites with device identifiers, our pages may appear in the results as new positional information when someone searches for those entities.
