  1. Foundations of Data Visualization & Programming

    6 weeks
    Goals
    • Master data visualization principles including perceptual encoding, chart selection frameworks, and color theory
    • Build strong Python data wrangling skills with Pandas, NumPy, and basic Plotly/Matplotlib visualization
    • Understand SQL fundamentals and be able to query relational databases for visualization-ready datasets
    • Learn Git basics and establish a reproducible workflow for data projects
    Resources
    • Fundamentals of Data Visualization by Claus Wilke (free online)

    • Kaggle Learn: Data Visualization micro-course
    • SQLBolt interactive SQL tutorial
    • freeCodeCamp: Git and GitHub for Beginners
    Milestone

    You can independently pull data from a SQL database, clean it in Python, and produce a well-designed, annotated Plotly or Matplotlib dashboard published to GitHub Pages.

  2. Interactive Web Visualization & JavaScript Mastery

    6 weeks
    Goals
    • Learn D3.js fundamentals for binding data to DOM elements and building custom interactive charts
    • Master Vega-Lite and Observable Plot for declarative, grammar-of-graphics-based visualization
    • Build proficiency in TypeScript and modern front-end frameworks (React preferred) for embedding visualizations in apps
    • Implement interactive features: tooltips, brush selection, linked views, and animated transitions
    Resources
    • D3.js official documentation and gallery examples
    • Observable HQ tutorials and community notebooks
    • Vega-Lite interactive examples and specification guide
    • React + D3 integration tutorials (Amelia Wattenberger's Fullstack D3)
    • Frontend Masters: D3.js and Data Visualization courses
    Milestone

    You can build a fully interactive, multi-view D3.js or Vega-Lite dashboard embedded in a React application, with linked brushing, responsive design, and smooth transitions.

  3. AI-Native Visualization & LLM Integration

    5 weeks
    Goals
    • Integrate OpenAI API and LangChain to build natural-language-to-chart pipelines
    • Learn to visualize high-dimensional embedding data using t-SNE, UMAP, and PCA with proper interpretability
    • Build dashboards for AI/ML model monitoring including drift, bias, and performance metrics
    • Work with vector databases (Pinecone, ChromaDB) and visualize retrieval results and semantic search behavior
    Resources
    • OpenAI Cookbook: function calling and structured output examples
    • LangChain documentation: chains, agents, and tool use
    • scikit-learn and UMAP-learn documentation for dimensionality reduction
    • MLflow and Evidently AI for model monitoring visualization
    • Pinecone documentation and embedding visualization tutorials
    Milestone

    You can build a prototype that takes a natural language question, queries an LLM, retrieves relevant data from a vector store, and renders an interactive, contextually appropriate visualization - all in one pipeline.

  4. Production Dashboards, Performance & Design Systems

    5 weeks
    Goals
    • Deploy production-grade dashboards using Streamlit, Dash, or Apache Superset with proper authentication and caching
    • Learn WebGL-based rendering for large datasets using deck.gl, kepler.gl, and regl
    • Build a shared visualization component library with Storybook, design tokens, and accessibility testing
    • Master real-time data visualization with WebSockets, Server-Sent Events, and streaming frameworks
    Resources
    • Streamlit and Dash documentation with deployment guides
    • deck.gl documentation and examples
    • Storybook documentation for component libraries
    • WCAG 2.1 guidelines for data visualization accessibility
    • D3 in Depth: performance optimization techniques
    Milestone

    You can architect and deploy a scalable, accessible, real-time dashboard system with a shared component library that serves multiple teams across an organization.

  5. Portfolio, Specialization & Job Readiness

    4 weeks
    Goals
    • Build 3-5 portfolio projects showcasing end-to-end AI visualization workflows across different domains
    • Specialize in one vertical (e.g., financial visualization, healthcare analytics, geospatial AI, or ML observability)
    • Practice system design for visualization platforms and prepare for technical interviews
    • Contribute to open-source visualization projects and publish technical blog posts for visibility
    Resources
    • Personal portfolio website built with Next.js or SvelteKit
    • Technical blog on Medium, dev.to, or personal site
    • Open-source contributions to Observable Plot, Vega-Lite, or Apache Superset
    • Blind / Levels.fyi for salary benchmarking and interview insights
    • Design portfolio platforms like Behance or Dribbble for visual work
    Milestone

    You have a polished portfolio with 3-5 production-quality projects, published technical writing, open-source contributions, and the confidence to ace interviews for AI Data Visualization Engineer roles.

Practice Projects

Apply your skills with hands-on projects. Ordered by difficulty.

Interactive COVID-19 Global Data Dashboard

Beginner

Build an interactive choropleth map and time-series dashboard using Plotly and Streamlit that visualizes global COVID-19 case data, vaccination rates, and mortality trends. Users can filter by country, date range, and metrics.

~15h
Python data wrangling with PandasPlotly choropleth and line chartsStreamlit layout and interactivity

D3.js Animated Data Storytelling: Global Climate Change

Intermediate

Create a scrollytelling data narrative using D3.js that guides users through climate change data - temperature anomalies, sea level rise, and CO2 concentrations - with animated transitions between views and contextual annotations.

~30h
D3.js enter/update/exit patternSVG animation and transitionsScroll-driven narrative design

LLM-Powered Natural Language to Chart Generator

Intermediate

Build a web application where users type natural language questions (e.g., 'Show me quarterly revenue by region') and the system uses OpenAI function calling to generate Vega-Lite chart specifications that render in real time.

OpenAI API and function callingVega-Lite specification designPrompt engineering for structured output

Embedding Space Visual Explorer for RAG Pipelines

Advanced

Build an interactive tool that connects to a Pinecone vector database, retrieves document embeddings, applies UMAP dimensionality reduction, and renders an interactive scatter plot where users can hover to see source text, click to inspect retrieval neighbors, and color by cluster or metadata.

ML Model Performance Monitoring Dashboard

Advanced

Design and deploy a Grafana-based dashboard that monitors a production ML model's key metrics: prediction latency (p50/p95/p99), feature drift (PSI/KS tests), data quality scores, A/B test results, and cost per inference - with automated alerts for anomaly thresholds.

~35h
