Pulsing Blood Vessels: A Figurative Approach to Traffic Visualization
IEEE Computer Graphics and Applications
|March 10, 2016
Summary
Semantic figurative metaphors in data visualization create evocative, emotional graphics but add non-data elements. This study explores the strengths and limitations of this approach using a Lisbon traffic example.
Area of Science:
- Data Visualization
- Information Design
- Human-Computer Interaction
Background:
- Data visualization designers use semantic figurative metaphors to create impactful graphic representations.
- Figurative metaphors aim to offer novel perspectives and evoke emotional responses.
- Incorporating these metaphors introduces non-data elements into visualizations.
Purpose of the Study:
- To survey the exploratory use of semantic figurative metaphors in data visualization.
- To analyze the strengths and limitations of employing figurative metaphors.
- To illustrate the application with a case study of traffic data.
Main Methods:
- Conceptual analysis of figurative metaphor use in visualization.
- Case study: Visualization of Lisbon traffic data as a circulatory system.
- Discussion of implications for data storytelling and design.
Main Results:
- Figurative metaphors can enhance engagement and emotional connection with data.
- The inclusion of non-data aspects may obscure or misrepresent the data.
- Effectiveness depends on careful design and clear communication goals.
Conclusions:
- Semantic figurative metaphors offer a powerful, albeit complex, tool in data visualization.
- Designers must balance evocative representation with data accuracy.
- Further research is needed to establish best practices for this visualization technique.

The vascular system, an integral part of the circulatory system, comprises various blood vessels that play crucial roles in maintaining the body's homeostasis. These blood vessels form a complex and efficient circulatory network. The three primary categories of blood vessels are the arteries, veins, and capillaries.
Arteries
Arteries circulate oxygenated blood from the heart, except the pulmonary artery, which transports deoxygenated blood to the lungs. Large arteries, such as the aorta,...

The human cardiovascular system comprises five primary types of blood vessels: arteries, arterioles, veins, venules, and capillaries, each serving unique functions.
Arteries and Arterioles: Arteries are muscular and elastic vessels that primarily carry oxygenated blood from the heart to body tissues, except for the pulmonary artery, which carries deoxygenated blood. They have thick walls to withstand high pressure and contain a layer of muscle tissue, allowing them to expand or contract as...

77.7K
Blood is pumped by the heart into the aorta, the largest artery in the body, and then into increasingly smaller arteries, arterioles, and capillaries. The velocity of blood flow decreases with increased cross-sectional blood vessel area. As blood returns to the heart through venules and veins, its velocity increases. The movement of blood is encouraged by smooth muscle in the vessel walls, the movement of skeletal muscle surrounding the vessels, and one-way valves that prevent backflow.

01:07Development of Blood Vessels

The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...

Blood is circulated throughout the human body through a network of blood vessels called the circulatory system. This system includes arteries that transport blood from the heart to various body parts. These arterial pathways divide into smaller vessels until they reach the arterioles, which further split into capillaries. It is within these minuscule capillaries that the exchange of nutrients and waste products takes place. After this exchange, the blood is collected by venules, which fuse to...

Blood flow through a cylindrical blood vessel can be mathematically described using the principles of laminar flow, a regime in which fluid moves smoothly in parallel layers. In this model, the velocity of the blood is not uniform across the cross-section of the vessel; rather, it varies with the radial distance from the center. The maximum velocity occurs along the central axis, decreasing progressively toward the vessel walls, where it reaches zero due to viscous drag.Approximating Blood...
