Now I released the plugin version on Github: d3-electrophoresis.
It simulates a fundamental DNA-measurering method — electrophoresis– which cuts DNA sequence with restriction enzyme. Restriction enzymes recognize a specific base pattern such as “ATTA”, and cut DNA at the point.
And in the gel, a vertical lane includes DNA segment cut by a restriction enzyme. long segments stop early(top side), short segments go far(down side). It forms bands in each lane, which represents a profile of DNA sequence.
The plugin is digital mimicry of electrophoresis, so you can cut not only DNA sequence, but also any texts with selected words.
Refuting to seek readable visualization:
It is not a type of data visualization for understanding data or storytelling.
It is a kind of type to help you seeking isomorphism between different subjects, such as electrophoresis on president Trump’s speech.
In the effort, you should think like that: if president’s speech is DNA, restriction enzyme is cutting word, so what is chromosome then? or virus? Do the DNA inherits anywhere?
Then you should made data visualization that can apply two subjects. If succeeded, the data visualization represents isomorphism between them.
There are similar topics in “Gödel, Escher, Bach: An Eternal Golden Braid” by Douglas R. Hofstadter.
I am going to write the detailed concept for that in the blog.

Importing resulted SVG in CGI scene:
I downloaded SVG of trump’s inauguration text by the chrome bookmarklet, SVG Crowbar.
And I imported the SVG in Blender, then use them as bands of gel in 3D scene.
The entire scene of two images above are CGI I made in Blender. It’s not perfect recreation of gel because DNA bands are shown only when the gel is subjected to UV light.
