What is data visualisation and why do I need it?

A simple definition of data visualisation is the graphical or pictorial representation of the data, with colours and different kinds of sensible charts. It enables the management or the decision makers to interpret, identify trends and opportunities in the dashboard. Data visualisation gives a clear picture of what’s happening in business in one single glance. It speaks to you in the form of stories which is easier to understand, highlighting the red and green signals of businesses. Data visualisation removes noise from the data, and tells a story, whilst highlighting useful information.
