Complete apps built with shinywidgets, from single-widget templates to multi-widget showcases.

Every app here runs as-is: open its page for the source, the widgets it uses, and how to run it. Showcases combine several widgets into a full app; templates are small starting points for one pattern. Filter by kind of widget with the categories on the right.

AOI workbench

Charts

Maps & geospatial

Draw areas of interest on a multi-band raster and get zonal stats and a bar chart per polygon, computed live from leafmap’s drawn_features() accessor – no server round trip…

Brain atlas explorer

Scientific

Jump the NiiVue crosshair to a named landmark from Python, click to look up the AAL region and MNI coordinate under it, and restyle the atlas overlay in place.

Chemical explorer

Charts

Scientific

Sliders and a plotly lasso jointly filter the same mols2grid grid in place, with a click-to-inspect detail card and a selection-to-SDF download.

Handwritten digits, with the average of your selection

Data exploration

Crossfilter 1,797 handwritten digit images in embedding-atlas, and Python reconstructs the pixel-average image of exactly the digits you selected.

Les Misérables network

Networks

networkx computes communities, degree, and shortest paths on the classic Les Misérables co-appearance graph; ipycytoscape draws and restyles it live, entirely in place.

Map + chart + chat

Charts

Maps & geospatial

A map, a bar chart, and an LLM chat all read the SAME ipyleaflet bounds() accessor, so panning, asking, and a chat-driven fly_to tool call always agree with each other.

pythreejs orrery

An animated multi-body scene exercising every pythreejs integration point at once – in-place position updates on a timer, a shared Picker, and the camera accessor.

Rhodopsin in motion

Charts

Scientific

Scrub or click through a real molecular dynamics trajectory, linked frame-for-frame to an RMSD chart, with click-to-inspect and a residue-range highlight – all in-place.

300,000 cells – lasso to explore

Charts

Two linked jupyter-scatter plots of 300,000 synthetic single cells, mirroring selected() between them, with Python-driven selection and camera presets.

Python stdlib import graph

Networks

Click a module in an ipysigma graph (built by statically parsing the interpreter’s own standard library with ast) and it recolors to show what it imports and what imports it.

Terrain explorer

Orbit a real DEM, click to read elevation at the cursor, fly to the high/low points, and toggle wireframe – all without rebuilding the k3d scene.

Live trading desk

Tables & grids

One streaming perspective table feeds a blotter grid and a treemap at once; value boxes recompute server-side from exactly the grid’s current browser-set filter.

World development dashboard

Maps & geospatial

A GDP-per-capita choropleth with a population-scaled city layer, where in-place restyles and lonboard’s view_state()/selected() accessors drive a live sidebar.

Weather brush

Charts

Brush a date range on an Altair timeline and see the matching days in a table and two value boxes, computed in Python from the selection.

Classifier playground

Charts

Input & drawing

Draw two classes by hand and watch a k-NN decision boundary refit live, next to a point count and a clear button.

Atlas explorer

Data exploration

An embedding atlas next to a live stat line and a detail table, both driven by the current brush selection.

Conway’s Game of Life

Input & drawing

Click cells to seed a pattern, then let a Shiny timer step the simulation – a clean starting point for any canvas app that mixes click-to-edit state with a Python-driven…

Network explorer

Networks

Pick a layout, click a node to see its neighbors – a small, adaptable starting point for exploring any networkx graph.

Spreadsheet

Tables & grids

An editable, cell-selectable grid with a status bar reporting Count/Sum/Average/Min/Max for whatever rectangle of cells you drag over, plus a live edit log.
