Won't render in Quasar

[sonicviz]

I tried testing this in Quasar and get the following error:
vue.runtime.esm.js?5593:619 [Vue warn]: Failed to mount component: template or render function not defined.

Imported correctly, registered component, added header to data, and add stub method for callbacks
