Bullet Charts with automatic updating
This example shows bullet charts—a compact alternative to gauges—for CPU load and memory usage. The charts automatically update their values every second by fetching the `bulletdata2.json` file. Using D3.js version 3.5, the code implements a custom `d3.bullet` function that renders range, measure, and marker elements as SVG rects and lines. Transitions with a 1000-millisecond duration animate the scale and element positions smoothly when new data arrives.

This is a follow on from the example that updated the charts with random data.
