Join Martin John Hadley for an in-depth discussion in this video Change map styles in Leaflet, part of R: Interactive Visualizations with htmlwidgets.
- [Instructor] When creating interactive maps,…one of the things people care about most…is how does the map look.…Are geographic features like mountains shown?…Is socio-political information…like country borders included?…Or do you simply want to a plain map…with the outline of the land masses of Earth?…Let's look at how we can customize…the appearance of maps in Leaflet.…In our exercise files, let's open up default-map-style.R.…I'm going to decrease the size of my environment…because I don't need it for this exercise.…
At the top of the script file, we load two libraries:…first is the tidyverse library for importing…and wrangling data and second is the Leaflet library…which we're going to use to create our interactive map.…I'll load this with Command + Enter…then on Line 4, I use read underscore csv…from the read.R library to import my CSV file…against the variable capital underscore cities.…Now, Lines 8 through 12 are where I've defined…my interactive map.…Let's evaluate this in steps.…
So, if I evaluate Line 8 and 9…

Start by learning to manage packages and structure data for visualizations with the tidyverse and the pipe operator. Then there is an important question: Which library should you choose? The course introduces five popular options: Leaflet, Plotly, Highcharter, visNetwork, and DataTables (DT). Instructor Martin Hadley shows how to use these libraries to create scattergeo, choropleth, and geolines maps; stacked bar charts, scatter charts, bubble charts, and heat maps; treemaps and time series charts; interactive networks and graphs; and responsive, interactive data tables. Plus, learn how to customize your visualizations with legends and tooltips, and extract click information for Shiny apps.
