Question: I want a platform that integrates with external tools to add charts and other elements to my PDF templates, do you know of one?

If you're looking for a service that can be integrated with other tools to add charts and other elements to your PDF templates, PDFMonkey could be the ticket. This automation service lets developers manage templates, add dynamic data and generate PDFs with a REST API. It has built-in chart support and can be used with tools like Tailwind CSS and QR Code generators.

Another option is Chartonomics, which is geared specifically to turning unstructured data into charts and other kinds of visualization. It supports more than 20 different chart types and has flexible pricing plans, so it could be good for quick visualization of complex ideas in business, education and other areas.

If you're looking for a more general-purpose PDF management service, you might want to check out LightPDF. It's got a broad range of PDF tools for document creation, conversion and analysis. It's not specifically designed for chart integration, but its feature set and professional API options make it a good option for developers who want to build PDF support into their apps.
