And their own text box on the chart confuses things even more - "Size of bubble represents average employment per establishment" - ?? The bubbles all look the same size to me...

Anna, they should be all roughly the same size, as employment per establishment has been always about 10.

Why use the bubbles at all, then?

there are charts for more then one industry. in some there is a decline in employment per establishment. in others employment per establishment has been more or less constant.

There actually is an interesting economic story in the employment per establishment data that is shown in the size of the marker on the charts. In the book and music store charts we see that the number of establishments and employment are both decreasing at about the same rate, so average employment per industry stays near constant. In the newspaper publishing chart the number of establishments and employment are both decreasing, but at different rates, such that employment per establishment has decreased over the last decade.

This makes sense: The number of employees in a retail store is less flexible. The number of employees at a newspaper is somewhat more flexible. Reporters can be paid to write the news stories, or the newspaper can be filled with stories from the wire service or other sources.
