Points on a graph conveys magnitude through the position. In Force Directed graphs the positions are simulated while the size of the point conveys the magnitude. Chandrasekaran is BIG. To find how big, just hovering your mouse reveals the information
Additional data points can be added to the circle using the colors, and other SVG shapes. It is truly possible to use the Force Directed graph, Simple. No Axes, No Legends. Information is conveyed. Idea to visualise the Bizheads is from VizHeads. That project has lot more going on. The headshots of Vizheads, their twitter handles and the size of the heads linked with the number of references. It all starts with Force Directed Graph.
Another inspiration is Pudding's Hamilton by Shirley Wu. This project is a massive effort and passion. We can see the information is shown without losing the emotion.
