During my computer science masters, there was a need to analyse data through plots. Analysing graphs and plots while blind is near impossible. Unable to see the lines or bars means you rely on sighted assistance or jumping through the data points with a screen reader. Jumping through the data points is easy with 20 or so data points, increase that to 20,000 and things get significantly harder.
With these issues in mind i focussed my dissertation around increasing accessibility to data. Part of the project is an audio plotting system built in python.
The intention was to create a system that was easy and fast to use. Plots can be generated for line, bar and histogram by passing through most data structures. Anything that contains numbers and is itterable will generate an audio stream. Below is a brief video demonstrating a test procedure for line plots.
