A few questions about billboard.js scatter chart

[AlleSchonWeg]

Hi,
i'm evaluate chart librarys if they met our requirements. Hopefully somebody can answer.

1. Can i replace the data points with base64 encoded images?
2. Can the data point be labeled?
3. Is there a algo to prevent data point label overlapping? Move label around the data point to find free space.
4. Can i use a "scaleLog" scale for x/y axis?
5. Zoom and panning available?
6. Is it possible to create a vertical gradient chart background which starts at top, first stop at a y=0 and last stop at the bottom?

Thank you
