I have revised my definition:
A graph is a specific database structure for storing data (a group of elements).
The structure itself gives additional information on the data by assigning certain rules (or meanings) to the graph’s building blocks: nodes and edges.
Nodes: members of the group that the graph displays.
Edges: the paths between members of the group (can be uni/bi directional)
There are many types of graphs, a common example for a graph is a “flowchart”, where the nodes are the “incidents” and the edges are the paths that connect them.
Another example is a “map”, where the nodes are “towns” and the edges are “roads”.
In biology, a graph can be used to represent many things: metabolic pathways, phylogenetic trees or even a table of codons for amino acids.
would be happy to get feedback :)
thanks,
