Each graph is accompanied by its numerical data

An image is often better than a long speech. Mais il peut être difficile de comprendre un graphique (courbe, diagramme, histogramme, camembert…) si l’on ne dispose pas des données qui ont permis de le créer. Par ailleurs, certains utilisateurs ne pourront pas avoir accès au rendu graphique : l’accès aux données leur permettra de comprendre les contenus.

Objectives

  • Allow or improve chart understanding.
  • Facilitate data sharing.
  • Improve accessibility of content to readers with disabilities.
  • Improve content support by search engines and indexing tools.

Implementation

  • For each graph representing numeric data (curve, chart, histogram, pipe… :
    • Display structured, in the context of the chart, all the numeric data it represents, for example in the form of a data table.
    • or provide in the context of the graph a link to content of the same type.

Control

  • Check the presence, for each chart, of structured content indicating all the numeric data it represents, or a link to a page providing it.

Validation

  • Needs to be verified by a human.
