What this video covers
Information visualisation is the practice of turning data into visual form - charts, graphs, maps, diagrams - so that patterns, comparisons and trends become visible at a glance. It works by mapping numbers to visual properties the eye reads instantly (position, length, colour, size), letting people see in a moment what a table of figures would take minutes to work out.
In the table, the pattern was buried - you'd have to read every number and do the maths in your head. As a chart, the same data shows its trend (and that one outlier) at a glance. That's information visualisation: mapping numbers to things the eye reads instantly. Just pick the right chart for the question, and keep it honest - the same power that reveals a pattern can fake one.
