Common Data Visualization Use Cases in Research and Open Source Investigations

Data visualization has a crucial role in research and open source investigations, helping analysts and investigators gain valuable insights from complex datasets.

Here are some specific use cases where data visualization is particularly relevant:

Political Economy Analysis

Political economy analysis involves understanding the interactions between politics, economics, and social factors.

Data visualization can assist in representing complex relationships and dynamics within a political system.

For example, visualizing campaign finance data can reveal connections between political candidates and donors, providing insights into potential conflicts of interest and campaign funding patterns.

Conflict Mapping

In conflict mapping, data visualization is instrumental in depicting spatial and temporal patterns of conflict, identifying hotspots, and understanding the dynamics between different actors.

By mapping conflict incidents, casualties, and displacement, visual representations can provide a comprehensive view of the conflict landscape and help identify trends and underlying causes.

Environmental Assessments

Data visualization is valuable for analyzing environmental data and assessing the impact of human activities on ecosystems.

Visualizing data on pollution levels, deforestation rates, or carbon emissions can provide a clear understanding of environmental challenges and guide evidence-based decision-making. Interactive maps and charts can also facilitate spatial analysis and help identify vulnerable areas and plan conservation efforts.

Social Network Analysis

Social network analysis involves studying relationships between individuals or organizations.

Network graphs can reveal hidden patterns and connections.

In open source investigations, visualizing connections between individuals engaged in illicit activities or organizations at different steps of illegal supply chains can shed light on complex relationships that might not be apparent through traditional analysis methods.

Public Health Research

Data visualization is vital in public health research by visualizing patterns and trends in disease outbreaks, epidemiological data, and healthcare disparities.

Heatmaps, time series graphs, and interactive dashboards help identify disease clusters, track the spread of infectious diseases, and inform public health interventions.

Fraud Detection

Data visualization is crucial in detecting patterns and anomalies that may indicate fraudulent activities.

By visualizing financial transactions, customer behavior, or employee activities, organizations can identify suspicious patterns or outliers that might go unnoticed through traditional analysis methods.

Interactive dashboards, network graphs, and anomaly detection visualizations enable investigators to uncover potential fraud schemes and take appropriate measures to protect assets.

Text Analysis and Natural Language Processing

In open source investigations involving large volumes of text data, data visualization techniques such as word clouds, sentiment analysis charts, or topic modeling visualizations can provide insights into patterns, trends, and key themes.

These visual representations assist in identifying relevant information, exploring connections between entities, and extracting meaningful insights from textual data.

In these use cases, data visualization allows researchers and open-source investigators to explore, analyze, and communicate complex information effectively.

By transforming data into visual representations it enables a deeper understanding of the subject matter and supports evidence-based decision-making.

It is worth noting that open source investigations often involve collecting and analyzing publicly available data from diverse sources.

Therefore, data visualization tools that can handle multiple data formats, integrate with APIs, and support data scraping capabilities are particularly valuable in these contexts.

Best Practices for Effective Data Visualization:

To maximize the impact of data visualization, following these best practices is crucial:

Understand the Audience

Tailor visualizations to the target audience’s knowledge, interests, and preferences.

Consider the level of expertise and the specific insights they are seeking. Remember that, more often than not, less is more.

Keep it Simple

Avoid clutter and unnecessary complexity. Use clear and concise labels, colors, and visual elements to convey the intended message effectively.

Ensure It Is Useful

We often see pretty visualizations that don’t deliver anything useful.

Be mindful of not visualizing data for visualization’s sake and ensure every graph produced provides actionable value.

Provide Context

Contextualize the data by including relevant labels, titles, and descriptions. Clearly define axes and units to ensure accurate interpretation.

Choose the Right Visualization Type for the Job

Select a visualization type that best represents the data and supports the desired analysis. They all serve different purposes and are optimized for different use cases.

Multiple chart types

Here are some types of charts available and their best-suited applications:

Bar Charts and Column Charts

Bar charts and column charts are popular choices for comparing discrete categories or groups.

These charts display data in rectangular bars or columns, where the length or height of each bar represents the value of the category it represents.

Bar charts are best suited for comparing different data points within a single category, while column charts work well for comparing data across multiple categories.

They are excellent for visualizing trends over time, analyzing survey results, and presenting categorical data like sales figures, market shares, or demographic distributions.

Line Charts

Line charts are ideal for showing trends and patterns in continuous data over time.

They use connected data points to illustrate the progression of a variable, making them perfect for visualizing time-series data, such as stock prices, temperature fluctuations, or website traffic over different periods.

Line charts enable viewers to spot trends, identify seasonal patterns, and detect changes in data over time with ease.

Pie Charts

Pie charts are effective for illustrating parts of a whole, displaying how a single data set is distributed among various categories.

The size of each slice in a pie chart represents the proportion of that category to the whole data set.

Pie charts are best suited for displaying relative percentages and helping viewers understand the composition of a whole, such as budget allocations, market share distributions, or survey responses based on multiple-choice questions.

Scatter Plots

Scatter plots reveal relationships between two continuous variables, each data point representing a combination of these variables.

They are useful for identifying correlations, clusters, or outliers in data and are particularly valuable for showing how two variables relate to each other.

Scatter plots are commonly used in scientific research, market analysis, and social sciences to visualize data points and identify patterns or trends in the data.


Heatmaps use colors to represent data values across a matrix or grid.

They are excellent for visualizing complex data sets, such as geographic data, customer preferences, or user interactions on a website.

Heatmaps are particularly useful when dealing with large datasets where individual data points can be difficult to interpret, but patterns and trends emerge when visualized in a heatmap format.

Remember, the choice of the chart type depends on the nature of the data and the specific insights you want to convey.

By selecting the appropriate chart, you can present data more effectively and ensure that your audience gains a clear understanding of the information being presented.
