Orange

Orange is an open-source data mining toolkit where users build analysis workflows by connecting widgets on a canvas. It needs no coding, which makes it popular for teaching as well as research.

What Orange offers

• Visual workflows: place widgets on a canvas, link them and load data to see results.
• Data visualisation: distributions, box plots, scatter plots, heatmaps and projections such as MDS and t-SNE.
• Machine learning: includes decision trees and hierarchical clustering.
• Add-ons: extensions cover text mining, network analysis, association rules, time series, survival data, spectra and gene expression.
• Teaching tools: some widgets were designed specifically for classroom use.

Customers and markets

Schools, universities and training courses use it for hands-on teaching, and scientists such as molecular biologists use it to analyse experimental data without programming.
