Wondering if it is possible the generation of ALT descriptions for SAS/GRAPH programmatically

[ikeplus]

Found and test an interesting Python library for generating alt text descriptions for plots made with Matplotlib.

The Library is Matplotalt https://matplotalt.readthedocs.io/en/latest/ 

Wondering if there is something similar for  SAS/GRAPH

Example using the heuristic method (no AI involved) 

the generated ALT text is: A bar chart titled 'world's biggest coffee drinkers (per capita)'. Average consumption (kg) is plotted on the x-axis from 0 to 14 using a linear scale and country is plotted on the y-axis from netherlands to finland using a categorical scale. (and the datatable in text, I am not posting here because format got damaged but providing screenshot)

I have a google colab with this example. if you want to read the python code.

@Ksharp the links your posted explain how to generate colorful graphs, but the question here is is there a way to automatically generate the ALT text that summarizes a graph (that would be displayed on hover, or for visually-impaired viewers with screen readers).   

That's a pretty cool feature.  I know SAS has done a lot of work on graphics accessibility, including translating graphs into audio representations: https://www.perkins.org/resource/sas-enables-visually-impaired-visualize-data/  .  But I don't recall seeing anything that would automatically generate an alt-text summary of a graph.

Thank you @Quentin , I will continue my search, for now my only possible solution is to upload via API the generated image file to an AI to get described the generated image with a WCGA compliant alt description. I will read more about SAS® Graphics Accelerator. have a beautiful day!

Assuming you don't find a SAS solution, you might suggest this as a product enhancement:

The LLM approach makes sense.  I haven't tried SAS Viya Copilot, but I wonder if SAS could adapt it to generate alt-text from graph images (or I guess from the data used to generate the graph).
