Orange
Orange Data Mining provides open-source machine learning and data visualization tools.
About Orange
Orange is a visual data mining and machine learning tool. Users build analysis workflows by placing widgets on a canvas, connecting them, and loading datasets, and the homepage states that no coding is needed for this. It offers interactive data visualization, including statistical distributions, box plots, scatter plots, decision trees, hierarchical clustering, heatmaps, MDS, t-SNE and linear projections.
Extensions add capabilities for specialized work, such as natural language processing, text mining, network analysis, association rules mining, fairness in machine learning, time series, survival data, spectra and gene expression data. The site says Orange is used at schools, universities and in professional training courses. The homepage offers a download of version 3.40.0, dated May 08, 2026. It also asks visitors to donate to fund bug fixes, new features, free educational content and computational infrastructure.
