Correct.

Correct.

Those last two steps are bonus and would be nice to have, if you want to reuse 
the code snippets. However, you could do it all in the template of the first

viewlets.

The simple way:

content/statistics.html
content/graph.png

statistics.pt

<table>...</table>
<img src="graph.png" />
