Big Data Visualization Techniques An Overview
An image can often convey whats exactly going on
and as per big data visualization is considered,
you may recall statements like a picture is
worth a thousand words. With its data
visualization techniques, though big data did the
vice versa turning facts and information into
pictures, making the decision-making process
easier for the viewers as in recognizing what the
data has to say and what effects are likely to
occur. Before we go to the depths, it would be
perfectly good to consider several basics. What
is Big Data Visualization?

via sina Big Data Visualization considers the
presentation of almost any type of data in
graphical format, making it easier to interpret
and understand. However, these presentations are
beyond any typical corporate histograms, graphs,
pie charts and any other representations like
this. These include even more complex
representations like fever charts and heat maps,
enabling a better exploration of information,
identification of correlations and unexpected
patterns. Scale is one of the defining features
of big data visualization. Enterprises can store
and manage large amounts of data that would have
taken numerous years for humans to create and
collect. Big Data visualization helps in
ingesting large amounts of raw corporate data
and processes it further into graphical
presentations which make larger analysis
possible within a few seconds. ALSO READ BIG
DATA SECURITY SECURITY ISSUES AND CHALLENGES IN
THE QUEUE Big Data Visualization Techniques There
are different ways of course for presenting data
from various categories. Depending on the cases
and situations, the following techniques may be
used Two-Dimensional (2D) Area

  • Such graphical representations are generally used
    for geospatial presentations i.e to showcase a
    certain geographic area or a specific location on
    the globe. These types of data visualization
    techniques are helpful when analysis on a
    large-scale is required. It is the best option
    to help the representation of voting results,
    demographics, business growth rates, tourism etc.
    The probable techniques of representation under
    this can be
  • Area or Distance Cartograms These are usually
    the copies of specific parts of several maps
    which also portray certain additional parameters
    like population size, demography, travel times
    or any other considered variables.
  • Choropleth this is a map using different colors
    for various specific representations of varying
    levels of the identified variable. For example
    the biggest inventory stocks or sakes level per
    state.

  • Dot Distribution Map This data visualization
    method uses dots for highlighting the level of
    the examined variable within an area.
  • Multidimensional Data Visualizations

  • via tapclicks
  • These are known to be the most widespread big
    data visualization approaches. In order to
    create an image that is easy to grasp it
    considers combining two or more dimensions. In
    case of depicting different values from a single
    data set, this is one of the best techniques.
    The probable ways of presentation under this are
    as follows
  • Pie Chart This is, of course, one of the most
    popular tools for data representation. A pie
    chart illustrates numerical values, split into
    sectors with angles and with angles and arcs
    proportionally set as per the values
    represented.
  • Histogram Representing both, time periods and
    value parameters, a
  • histogram is known o be a series of rectangles.
    It makes easier to grasp the dynamics of
    parameter adjustments.
  • Scatter Plot This data visualization model is
    known to depict two sets of
  • unconnected dots as parameter values.
  • Hierarchical Data Visualizations

5
  • via microsoft
  • Sometimes you are needed to show a comparison
    between two or more data value sets.
    Hierarchical or relation data visualizations
    stand out to be perfect for this.
  • Some considerable forms of presentations under
    this are
  • Dendrogram It is known to be the hierarchical
    clustering of various data sets which makes it
    easier to depict and understand the relations
    between them instantly.
  • Sunburst Chart Also known as the ring chart,
    this is basically a pie chart
  • with concentric circles which describe the
    hierarchy of various data values.
  • Tree Diagram This big data visualization method,
    presents the data structure with tree-like
    relations. These relations are generally
    presented upside down or from the left to the
    right.
  • Network Data Models

6
  • via interaction-design
  • When data sets are required to compared and
    related to each other, the network data
    visualization technique arrives as the best way
    of doing so. Here are the considerable
    presentations under this technique
  • Alluvial Diagram This is known to be the
    representation of a flow diagram that generally
    depicts the change in data structure over a
    considered period of time or under specific
    situations.
  • Node-Link Diagram This is a circular image
    consisting of dots which
  • represent dots which further depict lines and
    data nodes and the links between said nodes.
    Using this, the relation between data sources can
    be interpreted and the probable results can be
    recognized.
  • Matrix This is a chart or a diagram used to
    represent two or more data sets connected to
    each other via some relations. A matrix helps in
    showcasing the position of data sets against
    each other and also the relation they behold.
  • Temporal Visualizations

7
  • via niemanlab
  • Though they look like simple linear graphs,
    temporal visualizations are much more complex
    and descriptive images with several starting and
    finish points and some overlap items measured
    over them creating a descriptive image of
    variable adjustment. Below mentioned are the
    types of data visualization under this
  • Connected Scatter Plot It consists of a plot of
    values for two variables that are known to be
    fetched from a data set. Scattered over the
    picture these values are known to be connected
    with a line.
  • Polar Area Diagram This might create an image
    like a standard pie chart.
  • However, the difference is that the size of the
    sector is depicted by the distance from the
    center with respect to the angle and arc length.
  • Time Series This is one of the most used
    examples in case of continuous
  • data evaluations over a considered period of
    time. This is one of the best
  • data visualization techniques for the
    presentation of historical data.

    PROTOTYPES...
  • The above-mentioned data visualization techniques
    would be just the tip of the iceberg. There are
    still many more that can be successfully
    implemented. Approach is not an issue big data
    can make use of both traditional and special
    visualization techniques in order to make it
    understandable for various business users.
