If you’re interested in learning more about how to create beautiful dashboard applications in Python, check out our new book Python Dash.
You’ve seen dashboards before; think election result visualizations you can update in real-time, or population maps you can filter by demographic.
With the Python Dash library you’ll create analytic dashboards that present data in effective, usable, elegant ways in just a few lines of code.
Minute 1: Install Dash
Type the following command in your terminal/shell.
pip install dash
sudo pip install dash
Minute 2: Create Minimal Dash Project File “app.py”
Copy&paste the code into a new file called “
app.py” in a folder – with path
# file app.py import dash import dash_core_components as dcc import dash_html_components as html import plotly.graph_objects as go es = ['https://codepen.io/chriddyp/pen/bWLwgP.css'] app = dash.Dash(__name__, external_stylesheets=es) xs = list(range(30)) ys = [10000 * 1.07**i for i in xs] fig = go.Figure(data=go.Scatter(x=xs, y=ys)) fig.update_layout(xaxis_title='Years', yaxis_title='$') app.layout = html.Div(children=[ html.H1(children='Assets'), dcc.Graph(figure=fig)]) if __name__ == '__main__': app.run_server(debug=True)
Minute 3: Run Dash App
Open a terminal or shell in the
/path/to/dash_app/ and run
python app.py in it:
$ python app.py
Minute 4: Open Dash App in Your Browser
Copy or click on the IP address
127.0.0.1:8050 and open it in your browser.
