Preparing Scraped Data

How to get the data and put it in the right format? We show how to easily get the data from the web and transfer it to a file Orange can read. Read more >

Interactive Data Visualization

Perform simple data analysis with clever data visualization. Explore statistical distributions, box plots and scatter plots, or dive deeper with decision trees, hierarchical clustering, heatmaps, MDS and linear projections. Even your multidimensional data can become sensible in 2D, especially with clever attribute ranking and selections.

Visual Programming

Interactive data exploration for rapid qualitative analysis with clean visualizations. Graphic user interface allows you to focus on exploratory data analysis instead of coding, while clever defaults make fast prototyping of a data analysis workflow extremely easy. Place widgets on the canvas, connect them, load your datasets and harvest the insight!

Teachers and Students Love It

When teaching data mining, we like to illustrate rather than only explain. And Orange is great at that. Used at schools, universities and in professional training courses across the world, Orange supports hands-on training and visual illustrations of concepts from data science. There are even widgets that were especially designed for teaching.

Add-ons Extend Functionality

Use various add-ons available within Orange to mine data from external data sources, perform natural language processing and text mining, conduct network analysis, infer frequent itemset and do association rules mining. Additionally, bioinformaticians and molecular biologists can use Orange to rank genes by their differential expression and perform enrichment analysis.

"My laboratory produces large amounts of data from RNA-seq, ChIP-seq and genome resequencing experiments.  Orange allows me to analyze my data even though I don’t know how to program.  It also allows me to communicate with my collaborators, who are experts in data mining, and with my colleagues and trainees."

"The hyperspectral imaging and spectroscopy community is in need of tools that allow easy workflows and are capable of analyzing large amounts of data. Orange is a powerful platform to perform data analysis, see data flow and become more productive. It provides a clean, open source platform and the possibility to add further functionality."

"Orange is a great teaching tool, and students love it, because it is easy to use and it allows devoting attention to the high-level conceptual aspects of data mining. The program successfully helps to introduce data analytics to users with no programming experience."
