Daml Finance GUI for creating instruments

Was the GUI for creating instruments we have just seen during the Daml Finance webinar developed in-house or you use some open source library for that?

No ready-made 3rd-party library proved flexible enough to cover our needs with this, so we did a custom build using a mix of React and D3.js. Here’s the actual implementation: daml-finance-app/ClaimsTreeBuilder.tsx at adc298f2fa6a44b00fbc3ad4467d92c8a16d0a8e · digital-asset/daml-finance-app · GitHub

Thanks, will check it out!
