What can you do in the app?

  • Navigate the map, click through clusters of properties
  • Get price for individual marker (property)
  • Change the style of the map reactively
  • Set the number of properties
  • Set the range of the prices
  • Explore the actual distribution of prices
  • Observe code execution as it happens

From ggplot2 to plotly (example)

library(tidyverse);library(plotly)
p <- ggplot(data = diamonds) + 
  geom_bar(mapping = aes(x = cut, fill = clarity), position = "dodge")

ggplotly(p)

Using shiny, leaflet and plotly together

  • Shiny hosts the control widgets

  • Leaflet uses data interacting with Shiny's control widgets to generate the map

  • plotly visualises the output of the interactions converting a ggplot2 object to an interactive visualisation
