Offline interactive maps may be created with Highcharter. Data must be provided as GeoJSON.
- [Narrator] High Charter allows us to create…interactive choropleth like the map that you see here.…Choropleth are maps with defined regions,…for instance countries, which are shaded…according to a variable in your data,…in this example the population of the country.…What I really like about the High Charter choropleth…is as you move your cursor over the countries…you will notice that the legend at the bottom…indicates the current value of the population…in that country.…Let's go through how to generate…these kind of maps with High Charter.…
High Charter requires us to provide…our own region boundaries.…There aren't any built into the High Charter library.…For convenience, we'll call these boundaries shapefiles.…Obtaining good shapefiles is often a slightly…frustrating, multi stage process.…There are two steps.…First, find appropriate shapefiles,…and second, convert them to the GeoJSON format…that High Charter needs.…Now finding appropriate shapefiles is the most…time consuming part of creating good choropleth.…

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.
