The bubble graph triangulates the number of participants and the number of featured articles per participant with the total number of featured articles. In the graph, the total number of featured articles for each contest is illustrated by bubble size and label. As illustrated by the bubbles in the graph, similar to the rate of good articles per participant as the number of participants increases, the number of featured articles per participant seems to decrease. The four bubbles to the right of the 0.5 mark on the x-axis indicate that for those four contests there was at least one featured article for every two participants.
