Orange

About

Orange is an open source platform for data mining and machine learning that uses visual programming. You place widgets on the canvas, connect them, load your datasets, and analyze your data without writing code.

Orange offers interactive data visualization, from statistical distributions, box plots, and scatter plots to decision trees, hierarchical clustering, heatmaps, MDS, t-SNE, and linear projections. Specialized extensions add natural language processing, text mining, network analysis, association rules mining, and fairness in machine learning, along with support for data such as time series, survival data sets, spectra, and gene expressions.

Used at schools, universities, and professional training courses worldwide, Orange includes widgets designed especially for teaching. Users who want to support the project can donate to fund bug fixes, new features, free educational content, and computational infrastructure.
