# tensorplay.utils.viz.make_dot

Source: https://www.tensorplay.cn/docs/generated/tensorplay.utils.viz.make_dot.html

```python
tensorplay.utils.viz.make_dot(var, params=None)
```

Render the computation graph recorded for var.

Leaf tensors with requires_grad=True are drawn light blue and are
labeled by the name passed in params; the output tensor is light
green; recorded operations are white and labeled by operation name.

Parameters:

- var – output tensor whose recorded chain should be drawn.

- params – dict mapping a name to a leaf tensor, used for labeling.

Returns a renderable object: a graphviz.Digraph when the graphviz
package is installed, otherwise a matplotlib wrapper with the same
render(filename, format="png") call from the networkx fallback.
