Answer to: What kind of graph can make the data below easier on the end-user?

You'll need to understand the goals of summarizing the data before choosing a particular kind of graph or chart. Being "easier on the eyes" is not an actionable requirement. I would try asking readers what they mean by "easier on the eyes." What insights are they trying to find? Why are readers looking at this information, and what is their objective? What actions would people take based on the data? Answering those questions will lead you to which kind of graph is appropriate, and be mindful that multiple ways of presenting this data might be necessary to achieve all the goals.
