Can not able to plot Keras Model API  

Keras Model API  not supported with `ValueError: ANN Visualizer: Layer not supported for visualizing` 
I think this arises due to **Input** layer
my code is

```
from keras.models import Model
from keras.layers import Input, Dense

a = Input(shape=(32,))
b = Dense(32)(a)
model = Model(inputs=a, outputs=b)
model.summary()

ann_viz(model, title="My first neural network")
```
