Thank you for your feedback.
An implementation for Svelte is already planned, but thank you for the recommendation. I'll move the codebase of the Angular implementation into a seperate project soon which will make integrations for other JS frameworks pretty easy.
Your project looks very interesting and I'll definitely take a look into it.
The support for graph data is still in consideration. Offline/Local first support is planned and will definitely be a feature in the future.
Big thanks for the recommendations.
