Re: Making graphs built from large datasets accessible - helprequested

Years ago I worked with a blind statistician who worked on a gigantic 4000
cell table.
One strategy that worked in this situation was to divide up the huge Excel
spreadsheet into smaller chunks of data in linked worksheets (or tabs).

The final spreadsheet consisted of:
Tab 1, a table of contents that linked to the other tabs.
Tab 2, a summary of the individual worksheets/tabs with totals compiling the
data from all the worksheets/tabs.
Tabs 3, 4, etc. were smaller tables by topic. Tab 3 was blue widgets, Tab 4
was red widgets, etc.

Not only did it make it easier for him to navigate and use the spreadsheet,
but sighted users benefitted, too.

As a blind person, I'm very interested in these problems of communicating
complex ideas between the blind and sighted worlds. Unfortunately, I don't
have a solution.

What do users need to do with the information displayed in the data
visualization?

How do successful blind professionals navigate complex information or big
data sets? There must be a blind scientist, financial analyst, or
statistician who has adapted their own techniques for communicating about
big data.
