2. Outputs
Choose a sample or upload an image to see its description, structure, accessible visual, audio and data.
Description
Structure
Objects, properties and relationships as a tree. Use ↑ ↓ to move, → ← to open or close, Enter on a component to show it in the accessible visual.
Text outline
Accessible visual
Every component is focusable. Tab or arrow keys move between components; Enter asks “What is this?”. Click works too.
Move through the components to hear what each one is.
Audio
Speech synthesis is not available in this browser. The text description and structure tabs contain the same information.
Speak one component
Sonification
Hear the shape of a graph: pitch rises with the y-value while time sweeps along the x-axis (A3 to A5, two octaves).
Data
This visual has no numeric data series or table to extract. Its properties are in the Structure tab and the JSON export.
