Data visualisation, as the name suggests, gives visual representation of data and information. That is, it provides a clearer picture of what information means by providing visual context through maps or graphs. Data visualisation is mostly used to identify trends and patterns, data cleaning, exploring data structures and detecting outliers within large sets of data. It is a fundamental tool of modern data science.
