Data Visualization
The EDT includes many different types of variables for each
watershed and several methods for viewing and assessing these
variables. For example, the radar plots below provide a quick
overview of a specific watershed's condition. A radar plot can be
thought of as a histogram that has been bent into a circle with each
individual spoke representing a variable. Plots with more green
indicate watersheds with less degraded resources or fewer stressors.
Each individual spoke displays more green if the value of the
variable is good. If the value of a variable is bad for a watershed,
it will show less or no green. In the toolkit, the variable
descriptions show up in the interactive graph so that the user can
tell which variable is represented by each spoke.
The Lower Guyandotte watershed (first plot) exhibits better
ecological condition than the Lower Susquehanna watershed (second
plot).
