- Accessible Data Table (Accessible Table, Screen Reader-Friendly Table)
- A data table designed and implemented to be effectively navigable and comprehensible by screen reader users. Accessible data tables require proper HTML markup including table headers (th elements), sc…
- Auditory Graph (Audible Graph, Sonified Chart)
- A non-visual representation of data that uses sound properties such as pitch, volume, duration, and timbre to convey the values and patterns typically shown in visual charts and graphs. Auditory graph…
- Brushing and Linking (Brush and Link, Linked Highlighting)
- An interactive visualization technique where selecting or highlighting data in one chart automatically highlights the corresponding data in other linked charts within a dashboard. For example, clickin…
- Chartability (Chartability Heuristics)
- A set of heuristics for assessing the accessibility of data visualizations, developed by Frank Elavsky and the Dataviz Accessibility group. Chartability provides a systematic framework for evaluating …
- Choropleth Map (Thematic Map, Shaded Map)
- A type of thematic map in which geographic areas are shaded or patterned in proportion to a statistical variable, such as population density, income level, or unemployment rate. Darker or more intense…
- Composite Figure (Multi-panel Figure, Multi-element Figure)
- A figure that contains multiple distinct visual elements combined into a single image, such as a series of screenshots labeled (a) through (f), a set of charts showing different data sets, or a mix of…
- Content Element (Visual Content Element, Non-Text Content)
- A visual component within a document that conveys information beyond running text, including tables, charts, images, diagrams, equations, and code blocks. Content elements are often chosen for their a…
- Cross-Filtering (Interactive Filtering, Linked Filtering)
- A dashboard interaction technique where applying a filter in one component (such as selecting a category in a chart or using a dropdown widget) automatically updates the data displayed in other relate…
- D3 (D3.js, Data-Driven Documents)
- A JavaScript library for producing dynamic, interactive data visualizations in web browsers using SVG, HTML, and CSS. D3 gives developers fine-grained control over visualization rendering but does not…
- Daltonization (Recolouring, Color Remapping)
- Daltonization is a computational technique that modifies the colours in an image or on a screen to make them more distinguishable for people with colour vision deficiency (CVD). Named after John Dalto…
- Dashboard Accessibility (Accessible Dashboards)
- The practice of designing data dashboards — visual interfaces combining charts, key performance indicators, filtering widgets, and interactive data querying — so they are usable by people with disabil…
- Data Comics (Visual Data Comics, Narrative Visualization)
- An emerging genre of data visualization that presents complex information in a sequential, comic-like format with discrete panels that progressively reveal data and narrative. Data comics break down c…
- Data Physicalization (Physical Data Visualization)
- The practice of representing data through physical, tangible objects rather than on-screen visualizations. Data physicalizations encode information in the shape, texture, size, weight, or other physic…
- Data Sonification (Auditory Data Display, Sonified Data Visualization)
- The systematic mapping of data values to non-speech audio parameters such as pitch, volume, rhythm, timbre, or spatial location to make datasets perceivable through hearing. Data sonification is a key…
- Data Visualization (Data Viz, Information Visualization)
- The graphical representation of data and information using visual elements such as charts, graphs, maps, and diagrams. While data visualization is a powerful tool for communicating patterns and insigh…
- Data Visualization Accessibility (Accessible Data Visualization, Chart Accessibility, Visualization Accessibility)
- The practice of designing charts, graphs, diagrams, and other visual data representations so they are perceivable, operable, and understandable by people with disabilities, particularly those who are …
- Dynamic Tactile Graphics (Interactive Tactile Graphics, Animated Tactile Graphics)
- Tactile representations of visual information that can change, move, or respond to user interaction in real time, as opposed to traditional static tactile graphics which are fixed once produced. Dynam…
- Figure Accessibility (Chart Accessibility, Graph Accessibility)
- The practice of making visual figures, charts, graphs, and diagrams in documents and publications accessible to people who cannot see them, particularly blind and low vision users. Figure accessibilit…
- Gestalt Grouping Principles (Gestalt Principles, Gestalt Laws of Perceptual Organization)
- A set of principles from perceptual psychology that describe how the human visual system organizes individual elements into coherent groups and patterns. Key principles include spatial proximity (elem…
- Graphic Accessibility (Image Accessibility, Visual Content Accessibility)
- The practice of making graphical content — including charts, diagrams, maps, photographs, and illustrations — perceivable and understandable by people who cannot see them. Graphic accessibility encomp…
