The "Plots" option in the Context Panel branches to two choices: 3-D Implicit Plot, and Plot Builder. Figure 3.1.4(a) is the result of selecting 3-D Implicit Plot, along with the axis-order $x\,y\,z$. Notice that the grid density is modest, namely, ten points in each direction, and that $-5\le x\,y\,z\le 5$. Any modification to this graph would have to be done interactively, with the Context Panel for the graph, and with the Plot toolbar.

Figure 3.1.4(b) is generated with the Plot Builder where options can be applied before the graph is finalized. The default window $-10\le x\,y\,z\le 10$ in the Plot Builder (Basic Options) has been changed to $-3\le x\,y\,z\le 3$, and the Style changed to surfacecontour, Axes Style to frame, and (3-D Options) Lighting Model to none. The Grid Size (3-D Options) has been changed to $20\,20\,20$ from the default $10\,10\,10$, a change that means 8,000 sample points are used instead of the default 1,000.

Figure 3.1.4(b) can be obtained via the implicitplot3d command, implemented as shown below. (Select Evaluate from the Contour Panel.)
