5 online tools in data visualization playground

While building up an analytics dashboard, one of the major decision points is regarding the type of charts and graphs that would provide better insight into the data. To avoid a lot of re-work later, it makes sense to try the various chart options during the requirement and design phase. It is probably a well known myth that existing tool options in any product can serve all the user requirements with just minor configuration changes. We all know and realize that code needs to be written to serve each customer’s individual needs.

To that effect, here are 5 tools that could empower your technical and business teams to decide on visualization options during the requirement phase. Listed below are online tools for you to add data and use as playground.

1)      Many Eyes:
Many Eyes is a data visualization experiment by IBM Research and the IBM Cognos software group. This tool provides option to upload data sets and create visualizations including Scatter Plot, Tree Map, Tag/Word cloud and geographic Map plots.

For further advanced options, IBM offers Cognos product family for the enterprise customers.

2)      Circos :
Circos provides brilliant circular visualizations for exploring relationships between objects or positions. As part of its online utility, data set can be uploaded to generate visual representations and can be saved in online images.

Circular representations are useful when connections between objects are difficult to organize on a linear layout. This form of representation is also sometimes attributed as a ‘greedy layout’ since it tends to pack most data within the same page area. Also, it tends to appeal the narrower field of vision and therefore makes it a compelling option beyond the usual genomic studies use case.

Other libraries and tools which are known to support circular representation include D3.js and Datameer.

3)      Google Chart Tools :
From Google stable, Chart Tools has its usual Google usability stamp. It provides a customizable gallery of charts which are HTML5/SVG compliant. Further, it allows you to connect to a variety of data sources.

One can go to the online playground, paste in data in the script console and see output charts in real time. Some of the interesting charts options that one would like to explore include Gauge and Candlestick chart.

Another Google variant known as Google Fusion tables is also available as Chrome browser application.

4)      Color Brewer :

This is not a chart generating tool but rather a tool to help you decide color scheme for the charts. If it sounds trivial, then ask a data analyst on how he scratches his head for multi class data representation and how much he frets when he needs to take a print out for CEO on a monochrome printer.

Color Brewer is a diagnostic tool for “evaluating the robustness of individual color schemes”. It provides you option to design a color scheme with 3 broad categories:
(i) Sequential schemes – for ordered data that progress from low to high.
(ii) Diverging schemes - equal emphasis on mid-range critical values and extremes at both ends of the data range
(iii) Qualitative schemes - hues are used to create the primary visual differences between classes best suited for representing nominal or categorical data

Kuler from Adobe is another useful online tool for checking color schemes.

5)      Mr. Data Converter:
Mr.Data Converter is a simple online utility created by Shan Carter which helps to convert CSV or tab delimited data to web friendly formats including HTML, XML, JSON.  It is quite a handy utility for which source code is available on GitHub.

A few notes on these online tools:
-  It is possible your browser may not support large data sets in memory and may crash across.
- You would require Java and/or Flash enabled in your browser.

For further integration with these tools, refer to the additional API or scripts that these tools offer. Beyond these online tools, there are other highly useful libraries and desktop utilities also available across for download. For now, keep churning data and keep playing.

  1. Hi, what do you think about you can create custom data visualizations

  2. Well, then Knoema ( be easily added to this list as well.

    Creating visualizations in Knoema is based on a simple DIY process of making intelligible tables, charts, graphs, treemaps, interactive maps and so on.

    And to create any kind of visualizations one doesn't need to use just system datasets. Every user can also upload private data and mash up private data with data from public sources.

  3. NumberPicture is another awesome data visualization app that can be added to this list!

  4. Please also consider adding to your list. The recently launched tool lets you immediately convert your Excel or CSV data into several charts & visualizations to choose from.

  5. I prefer to use Lightroom and some templates from to make some data visualization in my science and educational presentations.

  6. Thanks for helping us understand this topic. You have written it in a way that makes it very simple to understand. Thank you so much. BIM documentation in USA

Data deduplication tactics with HDFS and MapReduce

As the amount of data continues to grow exponentially, there has been increased focus on stored data reduction methods. Data compression, single instance store and data deduplication are among the common techniques employed for stored data reduction. Deduplication often refers to elimination of redundant subfiles (also known as chunks, blocks, or extents). Unlike compression, data is not changed and eliminates storage capacity for identical data. Data deduplication offers significant advantage in terms of reduction in storage, network bandwidth and promises increased scalability. From a simplistic use case perspective, we can see application in removing duplicates in Call Detail Record (CDR) for a Telecom carrier. Similarly, we may apply the technique to optimize on network traffic carrying the same data packets. Some of the common methods for data deduplication in storage architecture include hashing, binary comparison and delta differencing. In this post, we focus o

In-memory data model with Apache Gora

Open source in-memory data model and persistence for big data framework Apache Gora™ version 0.3, was released in May 2013. The 0.3 release offers significant improvements and changes to a number of modules including a number of bug fixes. However, what may be of significant interest to the DynamoDB community will be the addition of a gora-dynamodb datastore for mapping and persisting objects to Amazon's DynamoDB . Additionally the release includes various improvements to the gora-core and gora-cassandra modules as well as a new Web Services API implementation which enables users to extend Gora to any cloud storage platform of their choice. This 2-part post provides commentary on all of the above and a whole lot more, expanding to cover where Gora fits in within the NoSQL and Big Data space, the development challenges and features which have been baked into Gora 0.3 and finally what we have on the road map for the 0.4 development drive.
