Circos: An Amazing Tool for Visualizing Big Data Storing massive amounts of data in a NoSQL data store is just one side of the Big Data equation. Being able to visualize your data in such a way that you can easily gain deeper insights, is where things really start to get interesting. Lately, I've been exploring various options for visualizing (directed) graphs, including Circos. Circos is an amazing software package that visualizes your data through a circular layout. Although it's originally designed for displaying genomic data, it allows to create good-looking figures from data in any field. When visualizing a directed graph, nodes are displayed as segments on the circle and the size of the ribbons is proportional to the value of some property of the relationships. 1. Let's start by retrieving the raw Google Analytics data. 02.analyticsService = new AnalyticsService(Configuration.SERVICE); 03.analyticsService.setUserCredentials(Configuration.CLIENT_USERNAME, Configuration.CLIENT_PASS); 07.query.setIds(Configuration.TABLE_ID); 18. 19.
Tagxedo - Word Cloud with Styles Articles table of contents methods All images in this article were created with Circos (v0.49) and the tableviewer utility tool. To obtain a manpage for any of the scripts, use the -man flag. > bin/make-table -man > bin/parse-table -man > bin/make-conf -man introduction This is the second part of a series of articles that describe how Circos can be used to visualize tabular data. In this article, I will cover the technical details of using the tableviewer set of scripts to parse your tabular data and turn them into files that Circos can use. tableviewer script set The tableviewer set of scripts is distributed as part of the circos-tools package and is composed of three scripts You CREATE your data file (or supply it), then PARSE it into an intermediate form, then FORMAT it to generate Circos input and finally VISUALIZE by running Circos. Figure Table visualizations are created using parse-table and make-conf. If you have your own data, you do not need make-table. CREATING DATA WITH make-table

Visualizing Tabular Data motivation For details about the methodology behind the use of Circos to visualize tabular data, see the article Visualizing Tabular Data. For an in-depth description of the configuration syntax for tableviewer script set, see Visualizing Tabular Data - Part II. script location tools/tableviewer script usage > cd tools/tableviewer > . The tableviewer is composed of three parts make-table - creates a random table (helpful for debugging and exploration) parse-table - parses a table into an intermediate state make-conf - uses output of parse-table and creates Circos data files and configuration files To get the full manpage, use -man. > cd tools/tableviewer > bin/make-table -man > bin/parse-table -man > bin/make-conf -man Adjust the configuration files in etc/ to suit your needs. details The scripts in tableviewer/ (make-table, parse-table, make-conf) generate a Circos image of tabular data. There are three scripts that compose the tableviewer package make-table or a large one

Help & Documentation Circos is a visualization tool created by Martin Krzywinski from the Michael Smith Genome Sciences Centre of Canada. Circos is a powerful command line tool that is particularly well suited for visualizing comparative genomics data, such as alignments, conservation and duplication events. Circos also supports drawing generalized 2D data in the form of line plots, scatter plots, heatmaps and histograms. Circos has an extensive variety of tutorials and tutorial images which provide information regarding the capabilities of Circos and the available options for creating images. The Circos User Interface (UI) was created to provide users with a simple way to use this powerful command-line tool. The Circos UI provides a wizard-like interface for configuring a run of Circos. On the Select Entry Points tab, a user can specify which entry points should be drawn in the image and also modify the appearance of entry points. NOTE: At least one entry point must be selected for drawing Label:
