I ensure that accessibility and design standards are thoroughly incorporated into the process of designing data visualizations. This includes implementing high-contrast type and colors, optimizing type size for efficiency, including a clear title and labels, and incorporating a filter mechanism. In cases where graphical charts are utilized, I make certain that a screen reader can interpret a text-based version of the chart, with the option to hide or show it as needed. Furthermore, I prioritize differentiation between data points within the charts, especially for users with low vision or color blindness. To enhance user experience, each visualization features an introduction or set of instructions at the top, followed by the relevant content. Utilize built-in styles and provide alternative text for better accessibility.
