I have a purely categorical dataset and want display in the form of an appropriate graph. The data is in the form of CSV. The data has information about enzyme names, biological pathway, organisms and the chromosome numbers they belong to. I want to display the chromosome to which these enzymes belong to by pathway and organism. Please let me know the best way to display this data. I know R and D3.js. Not sure whether these tools are good for this type of data or not.
