Background: Vaccination is one of the most successful public health interventions for the prevention of COVID-19. Toward the end of April 2021, UNICEF (United Nations International Children's Emergency Fund), alongside other organizations, were promoting the hashtag #***: The aim of this paper is to analyze the #VaccinesWork hashtag on Twitter in the context of the COVID-19 pandemic, analyzing the main messages shared and the organizations ***: The data set used in this study consists of 11,085 tweets containing the #VaccinesWork hashtag from the 29th to the 30th of April 2021. The data set includes tweets that may not have the hashtag but were replies or mentions in those tweets. The data were retrieved using NodeXL, and the network graph was laid out using the Harel-Koren fast multiscale layout ***: The study found that organizations such as the World Health Organization, UNICEF, and Gavi were the key opinion leaders and had a big influence on the spread of information among users. Furthermore, the most shared URLs belonged to academic journals with a high impact factor. Provaccination users had other vaccination-promoting hashtags in common, not only in the COVID-19 ***: This study investigated the discussions surrounding the #VaccinesWork hashtag. Social media networks containing conspiracy theories tend to contain dubious accounts leading the discussions and are often linked to unverified information. This kind of analysis can be useful to detect the optimal moment for launching health campaigns on Twitter.

Given a graph structure, different layout algorithms (even different settings of the same algorithm) usually result in different arrangements of vertices, and each layout may reflect certain aspects/parts of the graph more accurately than others. Thus, for high-level graph analysis tasks that rely on the overall arrangement of vertices, drawing conclusions only from one layout is risky. To alleviate the risk, we propose an ensemble framework to capture the commonalities and differences among possible layouts, and help users obtain a comprehensive view of the structure patterns. We leverage a set of layouts that represents the distribution of algorithm outputs. Then, visual features are extracted and analyzed based on various measures of visual similarity. Our framework supports users to analyze individual layouts in the context of the distribution, so that users can quickly identify structures of interest and discover patterns more accurately and comprehensively. We demonstrate the effectiveness of our framework by applying it to three datasets.

Network topology layout is one of the key technologies in the research of network topology structure. How to make the node overlap less and distribute evenly in the layout is an important and key problem in the research of network topological structure. Establishment of network topology generation algorithm based on node layout, design the node layout model, through node location layout and node linkage adjustment to achieve uniform layout, construction network topology generation algorithm, to achieves the effect from the physical topological structure to the logical topology beautiful display. The experiment shows that the network topology generation algorithm based on node layout has lower node coincidence ratio, point-edge crossover rate and better evaluation index, and the layout effect is better than other algorithms.

Background: Graph drawing is an integral part of many systems biology studies, enabling visual exploration and mining of large-scale biological networks. While a number of layout algorithms are available in popular network analysis platforms, such as Cytoscape, it remains poorly understood how well their solutions reflect the underlying biological processes that give rise to the network connectivity structure. Moreover, visualizations obtained using conventional layout algorithms, such as those based on the force-directed drawing approach, may become uninformative when applied to larger networks with dense or clustered connectivity structure. Methods: We implemented a modified layout plug-in, named Multilevel layout, which applies the conventional layout algorithms within a multilevel optimization framework to better capture the hierarchical modularity of many biological networks. Using a wide variety of real life biological networks, we carried out a systematic evaluation of the method in comparison with other layout algorithms in Cytoscape. Results: The multilevel approach provided both biologically relevant and visually pleasant layout solutions in most network types, hence complementing the layout options available in Cytoscape. In particular, it could improve drawing of large-scale networks of yeast genetic interactions and human physical interactions. In more general terms, the biological evaluation framework developed here enables one to assess the layout solutions from any existing or future graph drawing algorithm as well as to optimize their performance for a given network type or structure. Conclusions: By making use of the multilevel modular organization when visualizing biological networks, together with the biological evaluation of the layout solutions, one can generate convenient visualizations for many network biology applications.

Many real-world networks, including social and computer networks, have complex time-varying characteristics that evolve over time. Such dynamic networks are typically visualized using a sequence of timeslices, each timeslice presents the network topology at a particular time step. It is difficult to preserve the dynamic stability and visual continuity of the timeslices sequence, which allow researchers to interpret the temporal evolution of the network. In this paper, a dynamic network layout visualization method based on structural similarity is proposed to improve the quality of the timeslices. First, using network layout algorithm based on the community structure lay-outs a single timeslice and optimizing the layout through the static network cost function. Then, the new nodes are pre placed and the movement direction of nodes are constrained by a node movement method based on the s structural similarity, which can improve the dynamic stability and visual continuity of the timeslices sequence layout. Experiments show that the proposed method has a smaller layout cost in a single timeslice compared with the traditional dynamic network visualization, and a smaller node moving distance and the degree of structural shape change in the timeslices sequence.

Storyline visualization is a technique that captures the spatio-temporal characteristics of individual entities and simultaneously illustrates emerging group behaviors. We developed a storyline visualization leveraging dynamic time warping to parse and cluster eye tracking sequences. Visualization of the results captures the similarities and differences across a group of observers performing a common task. We applied our storyline approach to gaze patterns of people watching dynamic movie clips. We use these to illustrate variations in the spatio-temporal patterns of observers as captured by different data encoding techniques. We illustrate that storylines further aid in the identification of modal patterns and noteworthy individual differences within a corpus of eye tracking data.

An Automatic layout algorithm for BPEL Processes

An Automatic Layout Algorithm for BPEL Processes

The Business Process Execution Language (BPEL) is the standard execution language for business workflows. BPEL is an XML-based, verbose and complex language, consisting of block- and graph-oriented control structures, which makes it hard to generate intuitive visualizations. Although many tools enable the visualization of workflows before the transformation into executable systems, notations and style criteria for the visualization and layout of workflows are not standardized, so it is very hard to compare different tools. Often, the construction of a layout for a possibly complex workflow is left to the user or the result is visually unsatisfying. We present a novel algorithm for the layout of complex BPEL workflows, which uses the principles of the algorithm by Sugiyama and takes into account BPEL specifics, e.g. nested structures, parallel paths and several distinct types of elements. The BPEL specifics represent challenges to the layout algorithm and are not completely fulfilled by any other layout approach for BPEL.
