Digital image

As explained in Data Storytelling with Altair and AI

An image is a visual representation stored or rendered as graphical content.

A digital image gives a data story’s subject a concrete visual representation. Adding photos or illustrations clarifies context, guides interpretation, and can establish an emotional tone. section 8.5

Use images to strengthen a chart or visual narrative by:

  • Giving an abstract subject a recognizable face. section 8.5
  • Reinforcing a selected message, mood, or comparison. section 8.7
  • Adding generated visuals directly to an Altair chart through image URLs and mark_image(). section 4.5.2
  • Prefer original generated images when copyright restrictions make downloaded photos risky. section 5.4.2

A homelessness chart

A homelessness visualization uses two DALL-E-generated photos to represent homeless individuals. The images add context to the title and subtitle while making the topic more immediate. section 5.4 section 5.4.2
