# Topogram

This is a JavaScript implementation of [an algoritm to construct continuous area cartograms](http://lambert.nico.free.fr/tp/biblio/Dougeniketal1985.pdf), by James A. Dougenik, Nicholas R. Chrisman and Duane R. Niemeyer, ©1985 by the Association of American Geographers. It relies heavily on [d3](http://github.com/mbostock/d3) for rendering and [TopoJSON](http://github.com/mbostock/topojson) both for writing and reading topological JSON geodata.

The [included example](https://github.com/shawnbot/topogram/blob/master/index.html) combines TopoJSON-encoded and boundaries of the United States from [Natural Earth](http://www.naturalearthdata.com/downloads/110m-cultural-vectors/) with [2011 US Census population estimates](http://www.census.gov/popest/data/state/totals/2011/) to size each state proportionally.

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.

GitHub Actions: Input argument flows to dangerous sink

A GitHub context variable (such as issue title, PR description, or comment body) is being exported as an environment variable. These context values are user-controlled and could be exploited by subsequent workflow steps.

GitHub Actions: GitHub context variable exported as environment variable

A GitHub context variable (such as issue title, PR description, or comment body) is being passed back as an output. These context values are user-controlled and could be exploited by consuming workflows.

GitHub Actions: GitHub context variable passed back as output

A GitHub context variable (such as issue title, PR description, or comment body) flows into a dangerous sink (such as shell command execution). This is a critical security issue that could allow command injection or code execution attacks.

GitHub Actions: GitHub context variable flows to dangerous sink

An environment variable flows into a dangerous sink (such as shell command execution). If this environment variable comes from an untrusted source, it could be exploited to inject commands.
