Legends require that groups are set within node/edge data frames AND via visGroups. visNetwork supports Font Awesome icons for legends via the addFontAwesome() function.
- [Instructor] VisNetwork allows us to fairly easily…add legends to your network diagrams…for the use of the group column in the node data frame…let's see how to do that in our exercise files.…Let's load visNetwork-legend.R.…At the top of our script file,…we load the tidyverse library,…we Command + Enter.…And then the visNetwork library, we Command + Enter.…And then add data for the Games of Thrones universe…that we're going to visualize…comes from koggle.com,…and also from shiring's blog.…You can read about how I process this data…in the data-raw folder if you're interested.…
But here, we simply import the nodes CSV files,…and the edges CSV file.…We then use mutate from dplyr…to add a new column called group,…and we provide group with the column superculture.…So, now we're read to visualize our network.…So let's type visNetwork…GoT_nodes…GoT_edges.…Now if I were to display the network like this…by pressing Command + Enter,…we can see it take a couple of seconds…to display the network on screen.…
That's because we're using the built-in layout algorithms…
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.
