Data visualization is the process of representing data in a graphical or pictorial format, such as in charts, graphs, and maps. It is used in data science and analytics to help make sense of large and complex data sets, and to communicate findings to others. Data visualization can be used to identify patterns, trends, and outliers in data, and to communicate these findings to others in a clear and easily understandable way. Data visualization tools can include both static and interactive visualizations, and can be created using a variety of software and programming languages.
Data visualization is widely used in many real-world applications across various industries. Some examples include:
· Healthcare— Data visualization is used to analyze patient data and track the spread of diseases, monitor the effectiveness of treatments, and evaluate the performance of hospitals and clinics.
· Finance— Data visualization is used to analyze stock market trends, monitor financial performance, and detect fraudulent activity.
· Retail— Data visualization is used to analyze sales data, track consumer behavior, monitor inventory levels, and optimize pricing strategies.
· Manufacturing— Data visualization is used to monitor production processes, track equipment performance, and identify potential bottlenecks in the supply chain.
· Energy— Data visualization is used to monitor energy consumption, track renewable energy production, and optimize energy efficiency.
· Transportation— Data visualization is used to track the movement of vehicles and goods, optimize routes, and monitor traffic patterns.
· Social media— Data visualization is used to analyze social media data and track the spread of information, monitor brand reputation, and identify influencers.
· Public Sector— Data visualization is used to monitor crime rate, demographics, and other social indicators, to improve the decision-making and planning processes.
These are just a few examples, but data visualization can be applied to nearly any industry where data is collected, stored, and analyzed. The use of data visualization can help organizations make more informed decisions, and ultimately improve performance, operational efficiency and productivity.
Steven is a data visualization expert who understands the importance of effectively communicating data and model findings to diverse audiences. He has a proven track record of success, and recently helped a leading toy manufacture obtain valuable insights in its inventory levels, product sales, and organizational expenses through data engineering and reporting initiatives.
Through Steven's efforts, the client was able to access reports on a variety of devices, including tablets and mobile devices, and was trained to set alerts and notifications based on key performance indicators (KPIs) and thresholds. This increased visibility into organizational trends and helped departments with inventory management, sales, and marketing campaign effectiveness. By implementing data engineering and visualization strategies, the client rapidly advanced its analytic capabilities and integrated data governance, self-service, and data science into its operations.
Steven also employs data visualization techniques to effectively communicate exploratory data analysis results and model outputs to diverse audiences
Steven has a strong technical background in various data visualization tools such as Tableau, PowerBI, Qlik, Matplotlib and Seaborn (Python libraries). He is skilled in creating both static and interactive visualizations, and can use these tools to make data more accessible and understandable for stakeholders.

Steven has extensive experience in business intelligence and machine learning, and has developed interactive models that offer clients a unique dashboard experience. While traditional reporting methodologies are limited in their ability to support predictive, simulation, and optimization modeling, Steven's Interactive Models enable end-users to adjust model parameters and assumptions in real-time, supporting an infinite number of scenarios. These models include predictive, neural network, supervised and unsupervised machine learning, simulation, optimization, and forecasting models, and can be tailored to suit specific business requirements. Steven's approach enables organizations to extract additional value from existing models and continue leveraging them to enhance their analytical capabilities. The models are integrated into advanced dashboards, often using Tableau, Power BI, D3, Python, R-Shiny, and other cloud services.
Network diagrams have various practical applications. In this video, I illustrate how risk detection models can be combined with network diagrams to display the transmission of infectious diseases in the workplace.
In this video, I delve into additional applications of my MLB General Manager Dashboard. For a comprehensive understanding of the GM Dashboard, I suggest viewing Part 1 (link below) which dives deeper into the dashboard's optimization, prediction, and clustering models.
Using optimization and machine learning models, we've developed a Tableau dashboard that maximizes the Boston Red Sox's team roster and starting lineup based on a number of team, position, and player constraints. This dashboard uses Tableau's external client integration to recalculate model output in realtime using an R-Server.
When possible, Steven makes his work available for others to interact with and build upon. However, it should be noted that due to limitations in connecting to Python and R servers on Tableau Public, advanced modeling functionality may not be available on shared dashboards.
With embedded model parameters, users have the ability to run an infinite number of model scenarios in real-time, while also being able to save the model output for future reference and to grant access to others.
To effectively measure the outcomes of A/B tests, it's essential to establish a specific set of metrics and track them throughout the experiment. Steven was able to assist a struggling school district in monitoring the success of their student assistance programs, using these metrics to evaluate their effectiveness before scaling the programs to all schools in the district.
Have a use-case for interactive models or data visualization?
There are many resources available for learning about data visualization, including online tutorials, books, and courses. Some popular options include:
Ultimately, the best way to learn data visualization is to practice it, so it's recommended to start experimenting with different tools, data sets, and visualization techniques.
