Flow of Ideas: Crafting Creative Storytelling with Sankey Charts

Sankey diagrams, initially used in the 19th century to visualise energy flows in steam engines, have evolved into powerful tools for presenting complex data flows in various domains, from environmental science to economics, and, more recently, creative storytelling. In the domain of storytelling, the dynamic flow of ideas and emotions can be beautifully represented, enhancing the narrative experience for the audience. This article explores the creation and applications of Sankey charts in crafting creative storytelling, emphasizing their ability to convey complex ideas in a intuitive visual format.

Understanding Sankey Charts

A Sankey chart is a type of data visualization that uses a series of bars with orientations that represent and link different flows. Each flow is represented by the width of a bar, which is proportional to the flow rate or percentage. This type of visualization is particularly effective for displaying change over time or the flow from one state to another. In storytelling context, these can translate into emotional progressions, character relationships, or the transformation of themes.

Crafting Storytelling Flow with Sankey Charts

Defining Your Storytelling Flow: Before creating a Sankey chart for your story, clearly define the flow you wish to visualise. This could be the progression of a plot, the development of characters, or the transformation of themes. The more you understand your narrative flow, the easier it is to structure your Sankey chart effectively.
Creating the Sankey Chart: There are several tools available for creating Sankey diagrams, including dedicated software like Tableau and R programming language packages, such as ggsankey or ggplot2. Start by selecting your source and destination points, the direction of your narrative flow, and the proportional representation of your story elements.
Coloring and Annotation: Aesthetic choices like color selection can significantly enhance the storytelling aspect of your Sankey chart. Colors can represent different characters, themes, or narrative arcs, making the chart more engaging and intuitive for your audience. Adding annotations to each bar can further clarify the narrative flow, explaining the significance of each segment.
Interactivity and Presentation: If possible, incorporate interactive elements into your presentation. Some Sankey visualization tools allow you to add tooltips that explain the details of each point on the chart, making your story richer and more accessible. The timing and sequence of your audience’s interaction with the chart can be designed to mirror the pacing of your story.

Applications in Creative Storytelling

Character Development: Illustrate the evolution of characters through the narrative by creating a Sankey chart with different character personalities or goals intersecting and transforming over time.
Theme Evolution: Show the transformation of themes or underlying messages across various plot points or scenes. This can help in visualizing the thematic development of a story.
Plot Progression: Create a Sankey diagram with the major plot points or events leading to a climax or resolution, showcasing the interconnectedness and progression of the narrative.
Character Relationships: Model the relationship between characters, showing how they interact and influence one another throughout the story with a Sankey chart.

Conclusion

Sankey charts offer a unique way to visualize the flow of ideas and emotions in stories, making the narrative process more dynamic and engaging. By understanding the mechanics of Sankey chart creation and applying them to storytelling, creators can craft narratives that are not only compelling but also visually captivating. Whether for educational, narrative, or documentary purposes, these charts have the potential to revolutionize how we tell stories, making complex ideas more accessible and meaningful.
