Recently I finished working on a demonstration for a West Nile Virus map. I found myself referring back to my example often, so I thought that if it’s useful for me, maybe it will be useful for someone else!
Most of the data I was using was already in the public domain, but it only took a few edits to rely 100% on public data. Now I have a nice shareable example.
I’m not going to try an embed it into this post, here’s a link to the map, and here’s the source code for reference.
Also, I’ve started a github project to store some of my most often used map examples, hopefully that stay updated: https://github.com/geneorama/wnv_map_demo/
This is what the map looks like:
I did normal leaflet things, like used the values to control the circle size, customized opacity to make it easier to see the map below, and I made the red circle plot on top of the blue circle to give a sense of the proportion of mosquitoes affected.
However I learned some new tricks in this map:
- Of course,
data.tableprovides a fast and flexible way to manipulate and reshape the data
- I developed my own Mapbox template to mimic the look and feel of our Opengrid application
- I developed my own HTML pop-ups using

Happy mapping, and remember to use your DEET based bug repellent.
