# Demos A collection of little demos made using Makie graphics, which allows interactivity through the dragging of points or the use of simple controls. * `tangent-line`: see how the slope of secant line converges to the slope of the tangent line as `h` goes to 0 * `optimization`: Identify the optimal crossing point to minimize time when there are different velocities north and south of the x axis. * `inscribed-area`: Identify the maximal inscribed rectangle * `integration`: Compare visually the left Riemann approximation, the trapezoid method, and Simpson's method for different values of `n`. * `spirograph`: adjust parameters for the plotting of spirograph(https://en.wikipedia.org/wiki/Spirograph) patterns. * `bezier`: create Bezier curves by dragging control points.
