Virtual Graph Paper is a web application for creating drawings and illustrations on a virtual grid. It's free, and you can use it right here in your browser. Your drawing can be downloaded as a PNG or SVG file, or shared online using a unique URL.

An interactive 3D graphing calculator in your browser. Draw, animate, and share surfaces, curves, points, lines, and vectors.

This app illustrates how we plot various points in 3-space. To move the point up and down (parallel to the zAxis), click on it first before dragging it up and down. Click it again to move it around at the same level above or below the grid.

Apr 12, 2014 · Every so often I want to use R to plot a 3d graph, e.g. as below. This generates the plot just fine. but is there a more natural / efficient way of generating the x and y vectors? I want something like a "product" operator which gives me all possible pairs. Here's an easy way to to this using expand.grid and outer: thanks a lot!
