The matrix chart divides the screen into a grid. Rows represent the values in one text column (e.g., political candidate) and columns represent another text column (e.g., states of the US). Each cell then shows a circle or bar that represents the value for its row/column combination (e.g., contribution to Hillary Clinton from New York).
A type of scatterplot, this visualisation allows the representation of three variables. In the example, the plot presents the proportions of employment in the primary, secondary and tertiary sectors for 12 European countries in 1978, 1986 and 1997.
