Getting Started with Orange Tool

This blog is about using Orange Tool. Orange is a tool used in data science for various purpose. In this blog I would be taking you through some basic information about the Orange tool as well as how we will see some basic functionalities provided by the tool.

What is Orange Tool?

Orange is an open-source data visualization, machine learning and data mining toolkit. It features a visual programming front-end for explorative rapid qualitative data analysis and interactive data visualization (Source: Wikipedia). Some terms related to Orange are:

• Widgets: The various components present in Orange are known as widgets and they are divided into various categories like Data, Visualize, Model, Evaluate and so on.
• Workflows: Orange workflows consist of components that read, process and visualize data. We call them “widgets.” We place the widgets on a drawing board (the “canvas”). Widgets communicate by sending information along with a communication channel. An output from one widget is used as input to another.

How to use workflows in Orange?

here with Orange I have created a simple workflow wherein the inbuild Iris dataset provided by Orange is being used. The workflow is such that data from the dataset is sent to the data table, to distributions for creating a distribution and a Scatter Plot is plotted from the dataset.

To create this workflow we load the dataset using the File widget, and then flow between File-Data Info, File-Data Table, File-Distributions and File-Scatter Plot is created. In this way we can create a simple workflow in Orange.

sample workflow using orange

• To change data to be loaded in the Canvas, Double click on the File widget and select the data to be loaded here iris.tab file is selected.

Basic data exploration

As shown in sample workflow we can create workflow and after creating workflow we can check work done by double clicking on widget.

Distribution

Scatter plot

Load your data and load external data from API in Orange

To load your data in Orange select the File Widget and from there in you can either select the dataset provided by Orange or else browse to the dataset file in your local machine to load the data. If you want load external data use can select the URL option in the file widget, where one can paste the external dataset link to load the data.

Iris.csv file selected from storage

This is basic widgets and use of orange tool stay tuned for more.

Thank you!!
