CONTOUR CHART Meaning and
Definition
-
A contour chart is a graphical representation that displays the three-dimensional topography or variation of a certain variable on a two-dimensional surface. It is also known as a contour map or a topographic map, and is commonly used in fields such as geography, geology, meteorology, and engineering.
A contour chart consists of contour lines that connect points with the same value of the variable being represented. These contour lines are usually drawn at regular intervals, called contour intervals, which can be defined based on the data or the purpose of the chart. Contour lines on such a chart typically indicate areas of higher or lower values of the variable being measured.
Contour charts allow for a visual understanding of the spatial distribution and patterns of the variable across a given area. They provide an intuitive representation of how the variable changes and the relationships between different points on the surface. By observing the density and shape of the contour lines, one can identify areas of steeper or gentler slope, as well as areas with abrupt changes or smooth transitions in the variable being analyzed.
Contour charts are often accompanied by a legend or a color bar, which assigns specific values or color gradients to the contour lines, making it easier to interpret the chart. Moreover, technologies such as geographic information systems (GIS) enable the creation and interpretation of digital contour charts, allowing for more precise analyses and measurements.

Etymology of CONTOUR CHART
The etymology of the word "contour" can be traced back to the Latin term "contornare", which means "to mark the outline of". In English, the word "contour" emerged from the Old French word "contour", which referred to the outline or shape of something.
The term "chart", on the other hand, stems from the Late Latin word "charta", meaning "papyrus", which was derived from the Greek word "khártēs". Over time, "charta" came to refer to any kind of document or map, and eventually evolved into "chart" in English, referring specifically to a graphical representation or diagram.
Therefore, the term "contour chart" combines the notion of marking an outline or shape with a graphical representation or diagram, indicating a visual representation illustrating the shape or topography of something, often using contour lines.
