Objective: Build a CodePen.io app that is functionally similar to this: https://codepen.io/freeCodeCamp/full/xVopBo. Fulfill the following user stories. Use whichever libraries or APIs you need. Give it your own personal style. User Story: I can see a Force-directed Graph that shows which countries share borders. User Story: I can see each country's flag on its node. Hint: Here's a dataset you can use to build this: https://raw.githubusercontent.com/DealPete/forceDirected/master/countries.json Hint: You can create a spritesheet of national flags at https://www.flag-sprites.com. Remember to use Read-Search-Ask if you get stuck. When you are finished, click the "I've completed this challenge" button and include a link to your CodePen. You can get feedback on your project by sharing it with your friends on Facebook.
