Understanding charts and graphs often depends on access to the raw data. Providing this data ensures access to information when the visual representation is inaccessible or difficult to read.

Objectives

• Improve the comprehension of charts and graphs.
• Facilitate data sharing.
• Improve content accessibility for people with disabilities.
• Enhance content discoverability for search engines and indexing tools.

Implementation

• Identify every graphic representing numerical data (line charts, diagrams, bar charts, pie charts, etc.).
• Provide all represented numerical data in a structured format, such as a data table, in the immediate vicinity of the graphic.
• Alternatively, provide a link to the corresponding data in the immediate vicinity of the graphic.

Control

• Check that every chart and graph is accompanied by structured content showing all its numerical data or a link to a page providing this data.
