Introduction to Data
Visualisations and Analytics
Focused on tools used in Business Intelligence Industry
Data
facts and statistics collected
together for reference or
analysis.
Visualization
the representation of an
object, situation, or set of
information as a chart or
other image.
Why infographics are not the
same as data visualizations?
Infographics tell a premeditated story to guide the
audience to conclusions (subjective).
Data visualizations let the audience draw their own
conclusions (objective).

Data visualizations
Data visualizations are visual representation of data abstracted into a schematic
form so that the audience can more easily process the information and get a
clear idea about the data at a glance.
Data visualizations are:

Best for allowing the audience to draw their own conclusions, 

and offer objectivity 

Ideal for understanding data at a glance 

Automatically generated for arbitrary datasets
Maps Tables
Charts
