Re: Graphs and Alt Text

Meant to send this to the list, in case others are interested.

Daman,

My organization researched and published guidelines for writing alt text for graphs and other visual materials. Including an accessible data table is the recommended approach for graphs. Learn more at:

I am trying to figure out the best way to write alt text for line graphs.  I am wondering what techniques others have used.  Graphs are used to represent data quickly, but they also contain a lot of data.  How do I balance the amount of information?  I also have to find a technique that content editors can implement easily.  The only technique I can think of is to include an accessible data table with the data.  Looking forward to any input or suggestions.

Thanks in advance!
