Write short notes on Data Visualisation.

Data Visualisation is the process of communicating and translating data and information into visual contexts to make the data easier for the human brain to understand. It uses charts, graphs and other visual tools to represent analysed data in a graphical form. It communicates complex ideas more clearly, helps identify patterns or trends and makes large datasets easier to interpret. Common techniques include plots, charts/graphs, maps, timelines, network diagrams and word clouds.
