   en.wikipedia.org/wiki/Lissajous_curve

   A Lissajous figure, made by releasing sand from a container at the end of a Blackburn pendulum. A Lissajous curve / ˈlɪsəʒuː /, also known as Lissajous figure or Bowditch curve / ˈbaʊdɪtʃ /, is the graph of a system of parametric equations. which describe the superposition of two perpendicular oscillations in x and y directions of ...

3. Voronoi diagram - Wikipedia

   en.wikipedia.org/wiki/Voronoi_diagram

   Voronoi diagram. In mathematics, a Voronoi diagram is a partition of a plane into regions close to each of a given set of objects. It can be classified also as a tessellation. In the simplest case, these objects are just finitely many points in the plane (called seeds, sites, or generators). For each seed there is a corresponding region, called ...

4. Phase line (mathematics) - Wikipedia

   Phase line (mathematics) A plot of (left) and its phase line (right). In this case, a and c are both sinks and b is a source. In mathematics, a phase line is a diagram that shows the qualitative behaviour of an autonomous ordinary differential equation in a single variable, . The phase line is the 1-dimensional form of the general -dimensional ...

5. Venn diagram - Wikipedia

   en.wikipedia.org/wiki/Venn_diagram

   A Venn diagram is a widely used diagram style that shows the logical relation between sets, popularized by John Venn (1834–1923) in the 1880s. The diagrams are used to teach elementary set theory, and to illustrate simple set relationships in probability, logic, statistics, linguistics and computer science.

6. Cobweb plot - Wikipedia

   en.wikipedia.org/wiki/Cobweb_plot

   A cobweb plot, known also as Lémeray Diagram or Verhulst diagram is a visual tool used in the dynamical systems field of mathematics to investigate the qualitative behaviour of one-dimensional iterated functions, such as the logistic map. The technique was introduced in the 1890s by E.-M. Lémeray. [1] Using a cobweb plot, it is possible to ...

7. Plot device - Wikipedia

   en.wikipedia.org/wiki/Plot_device

   A plot device or plot mechanism[1] is any technique in a narrative used to move the plot forward. [2] A clichéd plot device may annoy the reader and a contrived or arbitrary device may confuse the reader, causing a loss of the suspension of disbelief. However, a well-crafted plot device, or one that emerges naturally from the setting or ...
