This example visualizes the recursive computation of the minimum number of coins needed to reach a target amount, using Python’s `Solution` class and its `coinChange` method. The code defines a depth-first search that memoizes intermediate results in a list `results`, checking whether the amount is already in the coin list or previously computed. It iterates over eligible coin values, recursively calling `coinChange` with a reduced amount, and updates the minimum count. A sentinel value of `-1` is returned when the amount cannot be formed. The visualization likely renders the recursion tree or state transitions based on this algorithm, though no graphical library is imported in the provided code.

This example demonstrates a linear programming optimization problem using the SciPy library in Python. It shows how to minimize an objective function with two variables, subject to two inequality constraints and lower bounds on both variables. The code defines the coefficients for the objective function and constraint matrix, then calls the `linprog` function with the simplex method to solve the problem. The result, including the optimized variable values and solver status, is printed to the console using the `print` function.

Mission Power

This visualization shows the relative scale of the transatlantic slave trade by country from 1501 to 1653, stacking separate area charts for each nation to compare activity over time. It uses D3.js version 3.5.5 to load tab-separated data from slavevoyages.org, map years to an x-scale, and draw smoothed areas with `d3.svg.area().interpolate("basis")`. Each country receives a distinct color, and vertical gridlines mark every 20 years, while the y-axis height encodes the annual number of enslaved people embarked.

Geoforms

Geoforms visualizes a 600-cell, a four-dimensional regular polytope, by projecting its vertices and edges onto a two-dimensional canvas using the hypersolid.js library. The data, sourced from Paul Bourke’s Hyperspace User Manual, is loaded from a `.ascii` file via `d3.text` and parsed with `Hypersolid.parseVEF`. An animated canvas displays the rotating shape, with checkboxes controlling six independent rotations in the `xy`, `xz`, `xw`, `yz`, `yw`, and `zw` planes. The animation loop uses `requestAnimationFrame` to continuously update and redraw the projection.

This example shows a static SVG canvas containing the text "Hello world!" rendered in a monospace font. The visualization uses the d3.v4 library, selecting the body element and appending an SVG element with a width of 960 pixels and a height of 500 pixels. It then appends a text element, positions it with x and y coordinates, and styles it with a font size of 36 pixels. The code demonstrates a minimal D3 workflow for creating a basic text visualization, with styles applied directly in the JavaScript rather than through CSS classes.
