automatic width/height setting - is this possible?

[GregH]

Q1 - Is it possible for google charts to automatically set the size of the resultant image based on how much data it has to plot?  If so how is this done?

Q2 - If not, how what is the best approach to ensure the image size returns fits well the amount of data presented?  That is, assuming my site may have a variable number of horizontal bars in a bar chart, how to appropriate scale/size the chart to fit the fixed size image?   i.e. if I have 3 bars versus 8 bars this affects how much "white space" seems to exist within the fixed image that is supplied.

thanks
