SEO-optimized Data Visualizations (e.g. Charts) Tools

[insurifyusa]

Hi there! We are currently evaluating data visualization / charting tools for rich content. Are there any open source solutions that work best in your opinion? Why? Some specific questions:

• Are static image / svg rendered images better than a javascript dynamic chart (canvas/HTML5)? Which gets indexed better?
• Is there any proven or perceived benefit to using Google Charts API that gives you an SEO boost?
• Are there tools for progressively enhancing HTML raw data tables to generate charts?

Looking at a couple of solutions:

• Google Charts API
• C3.js
• Chartjs

Thanks for your feedback!
