Are there any options for serializing an object (like a graphic) from the frontend?

Question

JavaScript

Hello.
I'm new to this, so I really need help.
Could you suggest an option that allows you to serialize the plotted chart displayed on the web application interface for further saving it as a BLOB in the database with the possibility of deserialization (the ability to reopen the chart object in the application interface without building it).
The application implies the possibility of plotting up to 200,000 points on a chart, therefore, getting each point from the database and reapplying it to the chart each time is not an option. Accordingly, it makes sense to save the graph already built once as an object. This is faster and then you can open and change the scale. But I don't know how to do this.
Help me please!

So JSON.stringify is the same.
