Wide formatted data frames are advised for bar charts. Data can be converted from long to wide via the gather function.
- [Instructor] Scatter charts, line charts,…and bubble charts are very useful charts…for visualizing a wide range of different datasets.…Let's look at how we can create these in a highcharter.…We'll open up our exercise file, scatter-and-bubble.R,…and we'll minimize the environment…because we don't need it for now.…At the top of our script file,…we can see we load the tidyverse.…We have library("tidyverse"),…which I'll run with Command + Enter,…and you'll notice, we don't actually load…the highcharter library, so let's do that.…Let's load library("highcharter").…
We'll hit Command + Enter,…and, as with every time we load the highcharter library,…we're reminded Highcharts is not free…for commercial or governmental use.…Now, to generate our scatter plot,…we need some scatter data.…So let's use read_csv to import a csv file…and store it against the variable scatter_data.…We can see printed in our console…a summary of the columns in our dataset,…and that's quite useful to just see.…We can see that there's an X column and a Y column,…
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.
