SoiferI VtP Annotation: Fire Landfill!

It would be helpful if the author more directly speaks to toxicity of place and how it fits within their argument and how the visualization specifically addresses it. Presently, it is difficult to decipher much from the visualization and how it's a representation of toxicity of place. It would also help if there is a brief description of what fire landfills are, and how they are physically and socially toxic, as well as where they tend to be located (a bit more context).
