Cartogram

A map in which the size of regions is distorted based on a particular variable.

Choropleth

A thematic map where areas are shaded or patterned in proportion to the value of a variable being represented.

Graduated Symbol Map

A map that uses symbols of varying size to represent quantitative data in specific locations.

Isoline Map

A map with lines that connect points of equal value, such as temperature or elevation.

Conformal Projection

A map projection that maintains accurate angles, preserving shape but distorting area.

Robinson Projection

A map projection that attempts to balance distortion of size and shape, presenting a more visually appealing representation of the Earth.

Equal Area Projection

Map projections that maintain area proportions, but distort shape.

Mercator Projection

A cylindrical map projection that preserves direction but distorts size, especially near the poles.

Gall-Peters Projection

An equal-area map projection that accurately represents the sizes of landmasses but distorts their shapes.

Goode's Homolosine Projection

A pseudo-cylindrical projection that shows equal-area but involves interruptions to minimize distortion.
