Before proceeding with the installation, you must have the following:

• A computer running macOS, Linux, or Windows with Bash installed.
• Node.js and npm installed on your computer.

const svg = d3.select('body').append('svg').attr('width', 50).attr('height', 50);
const circle = svg.append('circle').attr('cx', 25).attr('cy', 25).attr('r', 20);
