This example demonstrates a dynamic scatterplot of 50 randomly generated data points, where each point is represented as a circle. The visualization updates its scales and redraws the circles and axes when the user clicks on the text prompt, with each update using a transition that briefly highlights the circles in magenta before returning them to black. The code uses D3.js version 4.5.0 to define linear scales for the x and y axes, an SVG clipping path to contain the plot area, and transition methods to animate the data updates.
