We're not attacking RaphaelJS or any of these libraries. In fact, we use a modified version of RaphaelJS as the core, which we've open-sourced at https://github.com/fusioncharts/redraphael https://github.com/fusioncharts/redraphael These libraries are great to start with, and works well for many use-cases. Just that when your needs expand (think of additional chart types for specific use-cases, cross-browser compatibility including IE6/7/8, direct support from developers, assurance of continued development and fixes, meaningful implementations for different business scenarios etc.), our customers believe in us!
