This example displays a foot insole visualization, rendered as a smiley face shape using React. It shows the outline of the insole along with sensor positions and pressure values, with a side parameter indicating left or right. The code uses the `InsoleView` component from the `@feetme/insole-view-react` library, along with React and ReactDOM. The visualization is built from explicit coordinate arrays for the outline, sensors, and capacitance values, providing a direct mapping of sensor data to a geometric representation.
