How to use Simple Features in Maps with Plotly.
New to Plotly?
Plotly is a free and open-source graphing library for R. We recommend you read our Getting Started guide for the latest installation or upgrade instructions, then move on to our Plotly Fundamentals tutorials or dive straight in to some Basic Charts tutorials.
In order to complete the examples below, you'll require installing additional packages (
The examples below use the library simple features to read in the shape files before plotting the features with Plotly.
library(plotly) library(sf) nc <- sf::st_read(system.file("shape/nc.shp", package = "sf"), quiet = TRUE) fig <- ggplotly( ggplot(nc) + geom_sf(aes(fill = AREA)) ) fig
Using Native Plotly
Alternatively, you can use

Everywhere in this page that you see
fig, you can display the same figure in a Dash for R application by passing it to the
figure argument of the
Graph component from the built-in
dashCoreComponents package like this:
library(plotly) fig <- plot_ly() # fig <- fig %>% add_trace( ... ) # fig <- fig %>% layout( ... ) library(dash) library(dashCoreComponents) library(dashHtmlComponents) app <- Dash$new() app$layout( htmlDiv( list( dccGraph(figure=fig) ) ) ) app$run_server(debug=TRUE, dev_tools_hot_reload=FALSE)
