Semantigram

• Originally a one-day hackathon project.
• Since then it has grown to become something I've shwon off at YYC DataCon
• The concept is in two parts:
  1. Allow interoperable representations of data: visual diagrams, HTML, plain-text, tables, etc. Some of these formats ought to be accessible to the blind using semantic HTML.
  2. Allow changes to the data: highlights, edits, add/removes to be interoperably applied, regardless of the representation. Changes should be announced to screen-reader users in accessible formats.
• It combines semantics and diagrams.

TODOs/Dones

• Create a common data format to convert to:
  • SVG: Yes
  • SVG (tactile diagram): Not yet
  • HTML: Not yet
  • <table>: Yes
• Limitations
  • Data needs to be within the same order of magnintute (i.e., no support for logarithmic y axis)
  • No colour-blind palette
  • Uses JS
  • Lots of fixed values that aren't constified
  • Font size is small
    • Uses manual float/integer conversions in Rust
      • This should be fixed by using a arbitrary precision library that has support with askama.

Usage

To create the HTML file, and launch the websocket server, simply use the Makefile via the make command. Then, open the HTML file in a local browser.
