Static Maps with ggplot2
ggplot2 is a versatile data visualization package in R. It is primarily known for creating static plots and charts, including maps. To create static maps using ggplot2, we need to load spatial data and use the geom_sf layer to plot it.
R
# Load required packageslibrary(ggplot2)library(sf)library(maps)# Load and plot world map dataworld <- sf::st_as_sf(map("world", plot = FALSE, fill = TRUE))ggplot() + geom_sf(data = world) + labs(title = "World Map") |
Output:
Making Static & Interactive Maps With ggvis
- The globe map data is loaded using the map function from the maps package.
- The sf::The map data is transformed into a sf object, which ggplot2 may use for spatial data, using the st_as_sf function.
- A ggplot object is initialised by ggplot().
- The global map data is added to the plot using the geom_sf function, and the plot’s title is changed to “World Map” using the labs function.
Making Static & Interactive Maps With ggvis
In R Programming Language data visualization, making static and interactive maps is a common activity. Although the R package ggvis allows for interactive data visualizations, map visualizations are not one of its natural capabilities. For static maps and interactive maps, respectively, we commonly utilize tools like ggplot2 and leaflet.
In this article, we will check how to use ggplot2 and leaflet in R to generate both static and interactive maps.
