This a simple interactive map of the Elite:Dangerous Rare trades. That allows you to plot your own grand tour course.
Simply hover over each star, and click the ones you want. The table at the bottom shows your route with the best place on the route to sell each item.
The map is 2D the colour of the star is used to denote the Z position. From red below through yellow to white at the top. The actual distance between the current star and the star your hovering over is shown in the details box.
Simple Really. The data used is from the excellent spread sheet done here by Cmdr Dragonic
