How are nodes and links build from an ospf database

[ObaidAshiq]

i am building an ospf visualizer kind of thing in react As far as i have researched, You need 3 data things, from the terminal of a router And that we can get from these commands show IP ospf database show ip ospf database router show ip ospf database network You might also need show ip ospf database external which I am skipping not to increase the complexity of my project

The problem I am facing is how to create those arrays of nodes and links ? If u could guide me through, would be a great help
