  Most software applications contain graphics such as charts, diagrams and
maps. Currently, these graphics are designed with a ``one size fits all"
approach and do not cater to the needs of people with disabilities. Therefore,
when using software with graphics, a colour-impaired user may struggle to
interpret graphics with certain colours, and a person with dyslexia may
struggle to read the text labels in the graphic. Our research addresses this
issue by developing a framework that generates adaptive and accessible
information graphics for multiple disabilities. Uniquely, the approach also
serves people with multiple simultaneous disabilities. To achieve these, we
used a case study of public space floorplans presented via a web tool and
worked with four disability groups: people with low vision, colour blindness,
dyslexia and mobility impairment. Our research involved gathering requirements
from 3 accessibility experts and 80 participants with disabilities, developing
a system to generate adaptive graphics that address the identified
requirements, and conducting an evaluation with 7 participants with
disabilities. The evaluation showed that users found our solution easy to use
and suitable for most of their requirements. The study also provides
recommendations for front-end developers on engineering accessible graphics for
their software and discusses the implications of our work on society from the
perspective of public space owners and end users.
