* Should we allow more flexibility in the graphic format -- and how much? Limited formats could result in a cleaner user experience, as ugly or inappropriate formats would be excluded. On the other hand, it's an artificial restriction that prevents capable providers from creating innovative formats quickly. Rough potential ideas... | * Should we allow more flexibility in the graphic format -- and how much?

* Is Vista's high-dpi display mode stuff of interest here? We might want to be able to render a graphic in better quality given the ability. (ie, discourage raster-based graphic specifications) | * Is Vista's high-dpi display mode stuff of interest here? We might want to be able to render a graphic in better quality given the ability.

* How much (if any) control should the user be given over the display of the data source? For example, allowing the user to display a pie chart instead of a graph, or a week's worth of data instead of a month. To me, this primarily seems like a server-side thing, or maybe something a 3rd-party extension could expose. | * How much (if any) control should the user be given over the display of the data source?

* What kind of use-cases would be helped by this feature? | |||

The graphical part would ideally be represented by an <html:canvas> (or maybe even SVG?). I didn't have any luck with a test of that, although at worst it should be possible to have a hidden <canvas> render a data:// URL to display in the XUL's <image>. | The graphical part would ideally be represented by an <html:canvas> (or maybe even SVG?).
