  "Description": "Fit data to an ellipse, hyperbola, or parabola.\nBootstrapping is available when needed. The conic curve can be\nrotated through an arbitrary angle and the fit will still\nsucceed. Helper functions are provided to convert generator\ncoefficients from one style to another, generate test data\nsets, rotate conic section parameters, and so on.
