feature request - display chart from filename/url

[iliatimofeev]

Is it possible to show char from url like IPython.display.Image('my_image.png') do?

from vega import VegaLite
VegaLite(url='bar_chart_with_labels.vl.json')

You can load the json from file and pass the parsed dict.

With #33, you would be able to pass the file content directly but we don't support that yet.

In the spirit of separation of concerns, I would say that loading a parsing JSON is simple enough in Python and should be handled outside of this library.
