Perhaps the easiest way is to enter the data bars inside the cells. To do this, select the cells you wish to be analyzed and go under Home tab into Style section. From the row click on the first button called “Conditional Formatting”. From there click on “Data Bars” and apply the style of your liking. Another option would be to add icons inside the cells representing the values compared to other values in the selection. Again, go to the “Conditional Formatting” button and choose “Icon Sets” from the menu. This view offers more possibilities so hover over to see the preview and decide which suits you best. 

Best used for this is the scatter chart. Select your table only including cells that you wish to be presented on the chart and go under Insert tab into Charts section. Under “Scatter” choose the type of scatter that suits you best. Unfortunately no live preview is available on this case.
