# 3d plotting of sphere in SAGE

Hello, i entered this in my SAGE and the result is an empty space, not the sphere i wanted:

```
x, y, z = var('x,y,z')
sage.plot.plot3d.implicit_plot3d.implicit_plot3d(x^2+y^2+z^2==4, (x,-3,3), (y,-3,3), (z,-3,3))
```

what more is necessary to have the sphere i want :-(?

Try removing "sage.plot.plot3d.implicit_plot3d." from your code
