REST API with Swagger-UI published on Heroku: https://mysterious-ridge-97198.herokuapp.com/swagger-ui/

Endpoints according to requirements:

• creation of a user account: https://mysterious-ridge-97198.herokuapp.com/swagger-ui/#/User%20controller/createUsingPOST_1
• addition, view, modification, and deletion of quotes: https://mysterious-ridge-97198.herokuapp.com/swagger-ui/#/Quotes%20controller
• voting on quotes (either upvote or downvote). https://mysterious-ridge-97198.herokuapp.com/swagger-ui/#/Voting%20controller/voteUsingPOST
• view of the top 10 quotes, the details of each quote https://mysterious-ridge-97198.herokuapp.com/swagger-ui/#/Quotes%20search%20controller

I didn't have time to implement effective data extraction for graphs and rendering. Here is just an endpoint for data extraction for the graph. https://mysterious-ridge-97198.herokuapp.com/swagger-ui/#/Voting%20controller/getVoteStatisticsUsingGET (demo data filled for quoteId=1). Perhaps an interesting option would be to draw a graph on the front with animation, for example, using https://d3js.org/.

Demo data installed:

• 4 users
• 3 quotes from users 2-4
• 4 votes on quote #1 from users 1-4

PS: All actions except user registration are treated as committed by user #1 (login="test"), since authorization is not implemented.
