This interactive Sankey diagram visualizes global greenhouse gas emissions for 2005, sourced from the World Resources Institute, by showing the flow of emissions from energy, industrial processes, agriculture, and land-use change to specific gases like carbon dioxide, methane, and nitrous oxide. Built with the `d3.sankey()` plugin, it uses draggable, colored nodes and curved, semi-transparent links with hover titles to display quantities. The code customizes node width, padding, and layout iterations, and implements custom drag behavior via `d3.behavior.drag()` to reposition nodes and trigger `relayout()` for dynamic link updates.
