Hi @cpsievert , here's the link to the code: https://github.com/shreya2105/Shinyapps.
It's not so slow while loading but while processing the data on the leaflet map, the app takes forever. And, the legend box with the leaflet map almost shows up a minute after.
Within the app, the data in dropdowns is reactive. It's stored in an observe function. That's slow even when run locally. Not sure, how I can speed up that process.
Please let me know if you have trouble accessing it.
