Let’s explore how to use them to turn DZ business data into actionable intelligence.

TL;DR

• Plotly, Dash, and Streamlit form one of the most powerful Python stacks for dashboarding.
• Plotly handles interactivity, Dash builds enterprise-grade apps, Streamlit provides rapid prototypes.
• This guide covers how each tool works, how to build dashboards, real DZ business examples, and production tips.
• Includes code samples, comparisons, and optimization techniques.

What is dashboarding with Python and why does it matter for DZ businesses?

Python dashboarding refers to building data visualization interfaces, analytic tools, and web-based dashboards using Python rather than traditional BI platforms like Power BI or Tableau.

Why it matters in Algeria

Algerian companies increasingly face:

• rising data volumes
• complex performance tracking
• pressure for digital transformation
• the need for low-cost, customizable BI tooling

Python dashboards solve these challenges by offering:

• cost-free, full customization
• easy integration with internal databases
• automation of business reporting
• deployable apps accessible across teams

With Plotly, Dash, and Streamlit, you can build dashboards matching the level of commercial BI tools, but without licensing costs.

What are Plotly, Dash, and Streamlit?

Plotly

Plotly is an interactive visualization library for Python. It generates web-ready charts with zooming, filtering, tooltips, and animations.

It supports:

• bar/line/scatter charts
• geospatial maps
• 3D charts
• heatmaps
• statistical plots
• business KPIs
• highly interactive UIs

Dash

Dash is a framework for building full web applications using Python only.
It uses:

• Flask (backend)
• React (frontend)
• Plotly.js (visualizations)

Dash is ideal for:

• multi-page dashboards
• enterprise reporting apps
• advanced UI logic
• authentication and roles
• scalable deployments

Streamlit

Streamlit is the fastest way to build dashboards with minimal code.
Its strengths:

• extremely simple syntax
• ideal for internal dashboards
• rapid prototyping
• data science workflows
• startup-ready tools

Streamlit apps feel modern, lightweight, and easy to extend.

How dashboarding works in Python

How Plotly works under the hood

Plotly transforms Python objects into JSON specifications that a browser renders using JavaScript.
This separation makes charts fast, interactive, and responsive.

How Dash processes interactions

Dash uses callbacks.
User → UI event → Python callback → Visualization update.
All written in Python, no frontend coding required.

How Streamlit handles execution

Streamlit reruns the script from top to bottom whenever the user interacts with a widget, creating an extremely intuitive workflow for developers.

How to build dashboards with Python (step-by-step)

Step 1 — Install the tools

pip install plotly dash streamlit pandas numpy

Step 2 — Create your first Plotly chart

import plotly.express as px
import pandas as pd

df = pd.DataFrame({
    "Month": ["Jan","Feb","Mar","Apr"],
    "Sales": [120000, 150000, 170000, 165000]
})

fig = px.line(df, x="Month", y="Sales", title="Monthly Sales in Algeria (DZD)")
fig.show()

Step 3 — Build a Streamlit dashboard

# streamlit_app.py
import streamlit as st
import pandas as pd
import plotly.express as px

st.title("DZ Sales Dashboard")

df = pd.read_csv("sales.csv")

fig = px.bar(df, x="product", y="revenue", color="product")
st.plotly_chart(fig, use_container_width=True)

Run:

streamlit run streamlit_app.py

Step 4 — Build a Dash dashboard

# app.py
from dash import Dash, dcc, html
import plotly.express as px
import pandas as pd

df = pd.read_csv("sales.csv")

fig = px.line(df, "date", "revenue")

app = Dash(__name__)

app.layout = html.Div([
    html.H2("Algerian Sales Dashboard"),
    dcc.Graph(figure=fig)
])

if __name__ == "__main__":
    app.run(debug=True)

10 bonus tips for building dashboards with Python

1. Pre-aggregate large datasets

Never load raw millions of rows into the dashboard.

2. Use caching (Streamlit & Dash)

Helps avoid repeating expensive computations.

3. Optimize Plotly rendering

Reduce traces, simplify shapes, use WebGL when available.

4. Keep layouts clean

Users prefer clarity over complexity.

5. Add drill-down interactions

Allows deeper inspection of data.

6. Use lightweight CSS (Dash)

Improves performance and UX.

7. Separate computation from UI

Use dedicated files or modules.

8. Test dashboards on mobile

Many managers in Algeria check KPIs on smartphones.

9. Paginate tables

Avoid lagging browsers.

10. Deploy smartly

Options:

• Docker
• on-premise servers
• DigitalOcean or Azure
