I made an open source OSINT mapping tool. It includes a node based system for linking and keeping track of information as well. There is a free OpenStreetMaps option for the map. Or if you want you can use the Google Map option which requires a Google Maps API key.

Go check it out:

Edit: I forgot to mention that it's all local and web based. Nothing is stored on a cloud and all you need is a web browser and internet connection to get it working. Meaning it's accessible on every OS that supports a desktop.
