R Shiny web app to create Voronoi or sunburst treemaps. Available on Shinyapps.io!
Simply run the app at https://m-jahn.shinyapps.io/ShinyTreemaps/!
If you want to run ShinyTreemaps locally, you need to have R (optionally also Rstudio) and some of its libraries installed, mainly:
shinyshinyjsshinythemesshinyWidgetsdplyrcolorspaceWeightedTreemaps
Open server.R or ui.R in RStudio and push the Run App button in Rstudio, done!
You can also run the app from R console, just call runApp("path-to-ShinyTreemaps).
ShinyTreemaps is simply a GUI wrapper for WeightedTreemaps. Treemaps are a visually appealing graphical representation of numerical data using a space-filling approach. A plane or ‘map’ is subdivided into smaller areas called cells. The cells in the map are scaled according to an underlying metric which allows to grasp the hierarchical organization and relative importance of many objects at once. This package contains two different implementations of treemaps, Voronoi treemaps and Sunburst treemaps.
Features:
- Upload you own data tables (
*.csvpreferred, support for more formats planned) - Select columns (variables) you want to plot on the map. Selection should follow a hierarchical order from broad to more fine-grained
- Hit the "Make treemap!" button and start customizing your map
- The creation of the map and the styling can be customized by many different parameters
ShinyTreemaps consists of a set of R scripts that determine the functionality.
server.Rcontains the main body of functions. The server obtains input parameters from the GUI and adjusts the graphical output accordingly (changes charts on the fly)ui.RThe GUI contains the interactive modules such as sliders and check boxes.global.Ronly imports the external R librarieshelpbox.Rcontains info boxes for help, contact, and background information
- Table (e.g.
*.csv) in plain text format, with named columns in the first row (header)
