A contour line (also isoline, isopleth, or isarithm) of a function of two variables is a curve along which the function has a constant value, so that the curve joins points of equal value. It is a plane section of the three-dimensional graph of the function f(x, y) parallel to the (x, y)-plane. In cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes. The contour interval of a contour map is the difference in elevation between successive contour lines.More generally, a contour line for a function of two variables is a curve connecting points where the function has the same particular value.The gradient of the function is always perpendicular to the contour lines. When the lines are close together the magnitude of the gradient is large: the variation is steep. A level set is a generalization of a contour line for functions of any number of variables.

turning off the edge smoothing option might help
By its design, GIF is quite limited in quality especially with transparency on. If you got GIF with colored border around edges of generated image, you can turning off
Edge Smoothing option and try again.
This option will give crispy edges around generated image, but might lead to pixelated result, so please use it at your discretion. For more information, check our guide about improving GIF image quality.
