HTTP POST requests are accepted to the service at the root level. They should have the altair json blob in the json field of the request. A filename is generated and a png and html file is created to capture the provided charting data. The png filename is provided back to the client.
HTTP GET requests are accepted to the service at the root level. These should match provided resources from previous POST requests.
