Link to docs

It would be useful to have a link to the docs, either in the readme or the project description:

problem of display in JupyterHub

Hello,

I have tried to run some examples extracted from the documentation and I didn't succeed in displaying any figure.
I am under JupyterHub.
Standard HBox or VBox generated from other scripts work well. Only the ones issued from ipyscales don't work.
Any idea ?
Thanks.
Patrick

from ipyscales import NamedSequentialColorMap, ColorBar, LinearColorScale
from ipyscales.datawidgets import ScaledArray
from ipydatawidgets import DataImage
from ipywidgets import HBox, VBox
from IPython.display import display

delta = 0.025
x = y = np.arange(-3.0, 3.0, delta)
X, Y = np.meshgrid(x, y)
Z1 = np.exp(-X**2 - Y**2)
Z2 = np.exp(-(X - 1)**2 - (Y - 1)**2)
Z = (Z1 - Z2) * 2

scale = NamedSequentialColorMap(domain=(np.min(Z), np.max(Z)))
data = ScaledArray(data=Z, scale=scale, output_dtype='uint8')
img = DataImage(data=data)

VBox([HBox([img, ColorBar(colormap=data.scale, length=len(x))]),  scale.edit()]) # -> NOT WORKING
# OR
# VBox([img]) # -> NOT WORKING
# OR
# vbox = VBox([img])
# display(vbox) # -> NOT WORKING

Unexpected token in package.json

There is an unexpected token in the package.json file, maybe the first " token?

Error when installing the jlab extension

I get a ModuleNotFoundError when installing the jlab extension

Top and bottom tick label missing

I'm using the current release via pip and use this to display

        cm = NamedSequentialColorMap(color_map.name, domain=(self.vmin, self.vmax))
        self.bar = ColorBar(colormap=cm, length=self.render_size[1], orientation='vertical')

This resulted in the top and bottom tick label missing.

Edit: Turns out I tested Firefox with the wrong codebase. After correcting that, Firefox shows the same problem as Chrome.

The dev console in Chrome shows no related error AFAICT:

Any help would be appreciated. I'm really looking forward to replacing my crappy hand-drawn colorbars.
