Also, Square Pie Chart is a good chart to be added in an Infographic where such visualizations are common but in a corporate set up, I guess this wouldn’t find its day or probably, show up only rarely. But is a slightly tricky to implement in ggplot2 using the coord_polar(). in Data Visualization with ggplot2 / Overlay plots and Multiple plots For example, you can modify a stacked bar chart so that each column is the same height (and sections of a given bar are therefore proportional). They can be gone with stacked, normalized bar charts projected into polar coordinates, if I recall properly. The Pie Chart in R is very useful to display the region-wise sales, Countrywide customers, Sales by Country, etc. Ggplot2 does not have a specific geometric function to build pie charts. The data for the examples below comes from the mtcars dataset. The pie() function takes a Frequency table as input. The plots also don't appear in the output (see below). Details. The chart will have a single column, so the x coordinate will be set to 1. Pie Charts . In this post we will show how to make 3D plots with ggplot2 and Plotly's R API.

Each values decides the proportion of circle. It doesn't work because ggplot detects and suppresses code that commits crimes against visualization. Studies have shown that piecharts are hard to read. The message is a warning, rather than an error (in fact, that same warning occurred in the code posted by the package author on the page you linked to) and probably isn't related to the underlying problem you're experiencing. For example, bar or point charts can display the same data. Update: Looks like the author of ggthreed has just released ggrgl, a new, more general package for extending ggplot2 into the 3rd dimension: https://coolbutuseless.github.io/package/ggrgl/index.html. by Matt Sundquist Plotly, co-founder.
