I’ve used project Tycho to gather data on diseases spread by Blood feeding arthropods (Dengue, Plasmodium, West Nile Virus)
And Flooding occurrences :
From the flood Observatory Colorado
My main goal of the visualisation was to try and show that flooding causes a increase in diseases within the local area, as flooding provides an extremely suitable breeding ground for mosquitoes.
I mapped all occurrences of the diseases between a ten year time frame 2000-2010 , each sate is coloured. Darker shade of red being a larger amount of people with a disease.
I then overlay-ed a map containing all the location of flooding indicated by the blue circles. The larger the circles the higher the severity of flooding.
However as I’ve found there is no real correlation.
My Questions for the map are more so for formatting however any information on data to plot for a high correlation would be appreciated.
Should I change my colour scaling so that smaller differences are more visible? or is it important to show the similarity?
Should I remove the fill on the circles as some of the smaller states are harder to see ?
Is 10 years a large time frame and if so what is generally a suitable time frame? just under 223,000 records
Is there a better way of visualising the flooding?
