InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
I've used D3.js to create linking between nodes before (way more flexible than a treeview). There are a lot of other libraries out there that can do it as well.
This could be probably done with https://js.cytoscape.org/ as well, so maybe look into that.
