The first graph he designed was a bubble chart that had double logarithmic axes, with income on one axis and health on the other.
他设计的第一个图形是一个带有一对对数坐标轴的气泡图，一条轴显示的是收入，另一条是健康。

The forces acting on the departing bubble are also analysed. and the formulas for calculating the relative velocity and the velocity with which the bubble moves to the tube axis are obtained.
However, for plaques bent perpendicular to their rib axis, there can be a sharp decrease in strength when the bubble width exceeds half of the rib base width.
