chart.js has a tobase64image method; to support that you would need to overload the render method in Builder.php to use your own version of chart-template.blade.php within which you could adjust the generated js to replace the ctx dom element with an image that has its src set to the return of tobase64image.

Support for this could be added to laravel-chartjs.
