2.4.3 Big Data Visualization

Big Data refers to this massive volume of generated data. To visualise large
data, novel and more interactive data visualisation techniques are proposed.

Following are some techniques to visualise large data.

i. Box plot

Box plots, also known as box-and-whisker plots, are statistical

visualisations that summarise the distribution of a dataset. It provides
a succinct representation of the median, quartiles, and prospective

outliers. The box indicates the interquartile range (IQR), while the
margins represent the range within 1.5 times the IQR. Outliers are

displayed individually. Box graphs are useful for comparing multiple

datasets and identifying important statistics and outliers. Several data
visualisation tools and libraries can be used to construct them. Figure

2.5 below depicts the Box Plot.
