Well that would depend the type of graph you’re titling and what the information on the graph holds.
There are:
Bar graphs
Pie graphs
Line graphs...etc.
Then, you need to think about what
the graph is representing.
For example: you could say there is a bar graph determining how many 5th grade students prefer vanilla over chocolate ice cream. You could title this graph “preferred ice cream flavors”
Hope this helps!! Have a great night.
