Visual Data Exploration

Visual data exploration is the interactive process of examining datasets through graphical representations such as charts, maps, and dashboards to discover patterns, trends, and anomalies. Accessibility considerations are critical because conventional visualizations rely exclusively on visual channels, creating barriers for users who are blind, have low vision, or have colour vision deficiencies. Accessible VDE design incorporates screen reader support, sonification (auditory data representation), keyboard-navigable interactive elements, and sufficient colour contrast with redundant non-colour encodings to ensure the underlying data insights are available to all users.
