Jupyter widgets are powerful tools for building user interfaces with graphical controls, such as sliders and text boxes, inside a Jupyter notebook. Interactive widgets can also be rendered in Sphinx documentation, on nbviewer, and on static web pages. But Jupyter widgets are more than a collection of controls. They are also a framework that makes it easy to build custom GUI controls in the notebook. Examples of custom widget packages include libraries for interactive 2d charting (bqplot), 3D graphics (pythreejs, ipyvolume), mapping (ipyleaflet), and more.
Sylvain Corlay is a quant researcher specializing in stochastic analysis and optimal control and the founder of QuantStack. Previously, Sylvain was a quant researcher at Bloomberg LP and an adjunct faculty member at Columbia University and NYU.
