// Learn about API authentication here: https://plotly.com/nodejs/getting-started
// Find your api_key here: https://plotly.com/settings/api

require('plotly')(username, api_key);

var data = [
  {
    x: [0, 2, 4],
    y: [0, 4, 2],
    type: "scatter"
  }
];
var graphOptions = {filename: "privacy-true", world_readable: true, fileopt: "overwrite"};
plotly.plot(data, graphOptions, function (err, msg) {
    console.log(msg);
});
