I suppose i will abratact the creation of these once i have done more.

Ideas for this include:

• when specifying the digraph, read from a file that has just the content
• …

Here is an example of one: link

A nice thing to fix would be a switch to light and dark.

this is the sort of html currently using:

<img src="snippets_png/industry_pca_light.png" 
data-light="snippets_png/pcs_and_normal_distribution_light.png" 
data-dark="snippets_png/pcs_and_normal_distribution.png" 
alt="test image" style="width:100%; display:block; margin:0 auto;" >
