#-----------------------------------------

In order to start using Dash, we have to install several packages.

1. The core dash backend.
2. Dash front-end
3. Dash HTML components
4. Dash core components
5. Plotly

(1) Install Dask (https://dash.plot.ly)
In your terminal, install several dash libraries. These libraries are under active development, 
so install and upgrade frequently. Python 2 and 3 are supported. 
sudo pip install dash  # The core dash backend
sudo pip install dash-html-components # HTML components
sudo pip install dash-core-components  # Supercharged components
sudo pip install dash-table  # Interactive DataTable component (new!)
sudo pip install plotly --upgrade
sudo pip install dash_table_experiments

(2) python HelloDash.py

(1) Hello.py

# -*- coding: utf-8 -*-
import dash
import dash_core_components as dcc
import dash_html_components as html
app = dash.Dash()
colors = {
    'background': '#111111',
    'text': '#7FDBFF'
}
app.layout = html.Div(style={'backgroundColor': colors['background']}, children=[
    html.H1(
        children='Hello Dash',
        style={
            'textAlign': 'center',
            'color': colors['text']
        }
    ),
    html.Div(children='Dash: A web application framework for Python.', style={
        'textAlign': 'center',
        'color': colors['text']
    })
])
if __name__ == '__main__':
   app.run_server(debug=True,port=8080)

#------------------

(2)HelloDash.py

# -*- coding: utf-8 -*-
import dash
import dash_core_components as dcc
import dash_html_components as html

external_stylesheets = ['https://codepen.io/chriddyp/pen/bWLwgP.css']

app = dash.Dash(__name__, external_stylesheets=external_stylesheets)

app.layout = html.Div(children=[
    html.H1(children='Hello Dash'),
    html.Div(children='''Dash: A web application framework for Python.'''),
    dcc.Graph(
        id='example-graph',
        figure={
            'data': [
                {'x': [1, 2, 3], 'y': [4, 1, 2], 'type': 'bar', 'name': 'SF'},
                {'x': [1, 2, 3], 'y': [2, 4, 5], 'type': 'bar', 'name': u'Montréal'},

            ],
            'layout': {
                'title': 'Dash Data Visualization'
            }
        }
    )
 ])

if __name__ == '__main__':
   app.run_server(debug=True,port=8080')
