<strong>Objective:</strong> Build a <ahref='https://codepen.io'target='_blank'>CodePen.io</a> app that is functionally similar to this: <ahref='https://codepen.io/freeCodeCamp/full/xVopBo'target='_blank'>https://codepen.io/freeCodeCamp/full/xVopBo</a>.
Fulfill the following <ahref='https://en.wikipedia.org/wiki/User_story'target='_blank'>user stories</a>. Use whichever libraries or APIs you need. Give it your own personal style.
<strong>User Story:</strong> I can see a Force-directed Graph that shows which countries share borders.
<strong>User Story:</strong> I can see each country's flag on its node.
<strong>Hint:</strong> Here's a dataset you can use to build this: <ahref='https://raw.githubusercontent.com/DealPete/forceDirected/master/countries.json'target='_blank'>https://raw.githubusercontent.com/DealPete/forceDirected/master/countries.json</a>
<strong>Hint:</strong> You can create a spritesheet of national flags at <ahref='https://www.flag-sprites.com'target='_blank'>https://www.flag-sprites.com</a>.
