All,
On today's call, it was brought up that examples are needed. I prefer fully
expressive charts that use a rich taxonomy and directional navigation and
robustly populates the accessibility tree, but we don't have that in the
Graphics Module or SVG AAM and don't have user agent support yet. So I am
asking, what is the scope of the examples?
Are the examples supposed to show how tab index and the three roles can
make a SVG useful to a screen reader? For instance, are we looking for an
example of a stacked bar chart that works with tabindex alone? I don't
think we have sufficient markup to make a stacked bar chart work without
hacks. And I believe using flowto and links in most cases within an SVG are
hacks. Using flowto for connectors makes sense, but not in the case of
stacked bar chart where you simply need a way to drop to the next lower
level of the hierarchy or move back up a hierarchy. I would not want to
produce examples that teach people hacks. What do others think?
