Data visualizations are an increasingly popular way to present complex data sets. They transform raw data into visual formats like charts, graphs, maps, and diagrams, allowing some people to grasp patterns, trends, and relationships at a glance. However, if data visualizations are designed without accessibility in mind, they can present barriers due to their emphasis on visual presentation. For most data visualizations, you will need to present an alternative format to support all users.
