Graphing Node.js Memory Usage with D3.js and Rickshaw

In a continuation of their series on real-time data visualization, the blog post delves deeper into creating real-time charts by monitoring Node.js memory usage using Rickshaw, d3.js, and a specific npm module. This module seamlessly integrates with the Rickshaw-PubNub library, facilitating the logging of memory usage and the spawning of an express static server. The real-time memory usage is captured through `process.memoryUsage()` and published at regular intervals to a specified PubNub network channel. The post provides a step-by-step guide to setting up the module, which includes installing it via npm and configuring it to run on a local express server, ultimately allowing users to visualize and modify a real-time Node.js memory profile chart.
