Microservice that will run in lambda. It receives a JSON with information about the changes of a property over time. It creates a multiline graph, and then creates a PNG of that graph, and send it to S3 so it can embed on a Slack notification
In order to upload the function to Lambda, I did some changes in the server.js (No need for express.js, this is now Lambda role). So I created a folder called lambda, and there the server.js is modified, and there is some .so files, because I use Canvas module. It requires some C binaries.
