We probably need to provide a way to integrate widget without using web-component with just a plain JavaScript plugin.

Example of usage:

import createSkillsChart from '@codersrank/skills-chart/plugin';

createSkillsChart({
  el: '.some-element',
  skills: ['JavaScript', 'TypeScript'],
  // ...
})
