Hi LUGBZ,
Peter Moser explained in a webinar about how to create web components, which are web widgets. In general he shows how web components work and how to create them. At the end of the webinar he also shows how to use data from the Open Data Hub to populate the web component with real time data.
You can find the recording of the webinar on the NOI Techpark Youtube channel:
