How to Create a Treemap Visualization in Python?
Creating a treemap visualization in Python involves several steps, including data preparation, coding, and customization. Here is a step-by-step guide on creating a treemap visualization using one of the top Python libraries, Plotly:
Step 1: Data Preparation
The first step in creating a treemap visualization is to prepare the data. This involves organizing the data in a hierarchical format, such as a nested list or a Pandas DataFrame. For example, suppose we have a dataset containing information about sales revenue by product category and subcategory:
import pandas as pd data = { 'category': ['Electronics', 'Electronics', 'Furniture', 'Furniture', 'Fashion', 'Fashion'], 'subcategory': ['Laptops', 'Smartphones', 'Beds', 'Sofas', 'Tops', 'Bottoms'], 'revenue': [1000, 800, 1500, 1200, 500, 700] } df = pd.DataFrame(data)
Step 2: Importing the Library and Preparing the Data
The next step is to import the Plotly library and prepare the data for visualization. This involves converting the Pandas DataFrame into a format that Plotly can understand:
import plotly.express as px fig = px.treemap(df, path=['category', 'subcategory'], values='revenue')
Step 3: Customizing the Treemap
Once the data is prepared, users can customize the treemap by modifying various visual elements, such as colors, labels, and layout:
fig.update_layout( title_text='Sales Revenue by Product Category and Subcategory', title_x=0.5, margin=dict(l=0, r=0, t=25, b=0) ) fig.update_traces( marker=dict( colors=['#008080', '#4CAF50', '#FFC107', '#F44336', '#9C27B0', '#E91E63'] ), textfont=dict(size=12), hovertemplate='Category: %{category}\nSubcategory: %{subcategory}\nRevenue: %{value:,}' )
Step 4: Visualizing the Treemap
Finally, users can visualize the treemap using Plotly’s interactive interface:
fig.show()
By following these steps, users can create effective and informative treemap visualizations using Python and Plotly. By experimenting with different data formats, customization options, and visual elements, users can unlock the full potential of Python treemap visualization for data exploration and visual analysis.

Use colors that are easy to distinguish and avoid using too many colors, which can create clutter and confusion. Consider using color-blind friendly palettes to ensure that all users can understand the visualization.
Avoid Clutter
Cluttered visualizations can be difficult to interpret and understand. Avoid using too many labels, markers, or other visual elements that can create clutter. Use white space effectively to separate different categories and subcategories, and consider using hierarchical treemaps to display complex relationships.
Provide Clear Labels
Clear labels can help users quickly understand the data being displayed. Use descriptive and concise labels that accurately reflect the data being visualized. Consider using tooltips or hovertext to provide additional context and information.
Customize the Layout
Customizing the layout of the treemap can help users better understand the data being displayed. Consider using different layout algorithms, such as squarify or slice-and-dice, to display the data in different ways. Experiment with different aspect ratios, padding, and border widths to create a visually appealing and informative treemap.
Use Interactive Visualizations
Interactive visualizations can help users explore and analyze the data more effectively. Consider using tools like Plotly or Bokeh to create interactive treemaps that allow users to zoom, pan, and hover over different categories and subcategories. Interactive visualizations can also help users identify patterns and outliers more quickly.
Test and Refine the Visualization
Testing and refining the visualization can help ensure that it is effective and informative. Consider sharing the visualization with colleagues or stakeholders to get feedback and suggestions for improvement. Experiment with different data formats, customization options, and visual elements to create the most effective and informative treemap possible.
By following these best practices, users can create effective and informative treemap visualizations in Python that enable them to explore and analyze complex hierarchical data quickly and efficiently.
