What is an isoline map?
An isoline map is a way of presenting numerical data cartographically, helping readers to recognize geographical patterns and relationships. Isolines are lines drawn on maps connecting data points of the same value. Isolines should have equal intervals between them numerically, and if shaded in a choropleth manner, the map can be known as an isopleth map.
