A graph is a well defined data type used in computer science to represent a lot of concepts, like the cities on the Travelling salesman problem or nodes in a network. It is something like this:
In some languages, like Portuguese, there is a different word for this data type ("grafo") and for other use of graphs ("gráfico"). But in English, the word graph is also overlapped with the concepts of chart, plot or diagram.
This makes searching for specific results near impossible. For instance, "recommended program to draw graphs" yields "Excel", even though it does not support the kind of graph I was looking for.
Is there any solution for this problem, when searching for adequate terms to reference a computer science graph, like a better and well-defined synonym for it?
