The sample code says graph.series_json returns

"[{"data": [[1, 1], [2, 2], [3, 3]]}]"

...whereas in reality my sample code returns

"[{"line": {"show": true}, {"data": [[1, 1], [2, 2], [3, 3]]}]"

Using latest pyflot from github as of today, latest jQuery, python 2.7.1.

It would appear that the "line" part should have been in options.
Needless to say, no graph is shown.
Removing the "line" part allows for graph to show.

What's the story?
