This study analyzes the impact of validator behavior on investor rewards in proof-of-stake (PoS) based blockchain networks and proposes a visualization system to assist investors in selecting appropriate validators. This system enables personalized evaluations through five adjustable indicators tailored to the investor's preferences. By utilizing similarity-based circular visualizations and radar charts, it facilitates the selection and comparison of validators. Additionally, it provides time-series data-based line graphs and raw data-based table views to support detailed comparative analysis among validators. The introduction of such a multifaceted evaluation methodology in staking investments is expected to contribute to the formation of user-customized portfolios and the establishment of optimized investment strategies.

In Brazil - a developing country and one that in its last census in 2010 presented a number of five-year interstate migrations of approximately 4.6 million people - the study of internal migration is a complex exercise given the size and diversity of the country. We adapted the chord diagram plot to visualize the bilateral interstate migration flows in Brazil over a five-year period of 2005-10, and the migration stocks in Brazil in 2010. The bilateral migration flows highlight some recent trends of interstate migration (observed in recent decades), in turn different from cumulative flows over a long period (migration stocks). Brazilian internal migration in the new millennium seems to be marked by the inability of destination areas to absorb migrants over long periods, by the return migration to areas of origin and by the emergence of new areas of retention of migrants.

We adapted the chord diagram plot to visualize China's recent inter-provincial migration during 2010-2015. The arrowheads were added to present the direction of the flows. This method allows us to show the complete migration flows between 31 provinces in China including the direction and volume of the flows. The spatial component was also clearly depicted in the plot using four color palates representing four regions in China (i.e. East, Center, West, Northeast) and arranging the 31 provinces in an approximate geographic order. Besides that, we extend the chord diagram plot to describe China's bilateral net migration during 2010-2015.

Infographics are visual representations designed for efficient and effective communication of data and knowledge. One crucial aspect of infographic design is the interplay between text and visual elements, particularly in circular visualizations where the textual descriptions can either be embedded within the graphics or placed adjacent to the visual representation. While several studies have examined text layout design in visualizations in general, the text-visual interplay in infographics and its subsequent perceptual effects remain underexplored. To address this, our study investigates how varying text placement and descriptiveness impact pleasantness, comprehension and overall memorability in the infographics viewing experience. We recruited 30 participants and presented them with a collection of 15 infographics across a diverse set of topics, including media and public events, health and nutrition, science and research, and sustainability. The text placement (embed, side to side) and descriptiveness (simplistic, normal, descriptive) were systematically manipulated, resulting in a total of six experimental conditions. Our key findings indicate that text placement can significantly influence the memorability of infographics, whereas descriptiveness can significantly impact the pleasantness of the viewing experience. Embedding text placement and simplistic text can potentially contribute to more effective infographic designs. These results offer valuable insights for infographic designers, contributing to the creation of more effective and memorable visual representations.

One of the possible consequences of the tightening of international borders during and after pandemic COVID-19 is what the World Economic Forum refers to as the 'throttling' of international (labour) migration. While this will have a profound macroeconomic impact on the global economy, the potential impact on remittances on families, communities and national economies could be equally marked. We present a chord diagram to visualize the latest inter- (and intra-) regional global data on international remittances. This graphic shows the degree of the interconnectedness of the 'global economy of work' and the extent to which negative health, economic, social or political changes for migrants in one territory will have profound consequences far across the world.

Background: Standard graphical tools for whole genome comparison require a reference genome. However, any reference is also subject to annotation biases and rearrangements, and may not serve as the standard except for those of extensively studied model species. To fully exploit the rapidly accumulating sequence data from the recent sequencing technologies, genome comparison without any reference has been anticipated. Results: We introduce a circular genome visualizer to compare complete genomes of closely related species. This tool visualizes the position of orthologous gene clusters rather than actual sequences or their features, thereby achieving the comparative view without using a single reference genome. The essential information is the matrix of orthologous gene clusters whose positions (not sequences) are color-coded in circular graphics. As a demonstration, comparison of 14 Lactobacillus paracasei strains and one L. casei strain revealed not only large-scale rearrangements but also genomic islands that are strain-specific. Comparison of 73 Helicobacter pylori strains confirmed their genetic consistency and also revealed the three general patterns of large-scale genome inversions. Conclusions: From the ample sequence information in the GenBank/ENA/DDBJ repository, we can reconstruct a genomic consensus for particular species. By visualizing multiple strains at a glance, we can identify conserved as well as strain-specific regions in multiply sequenced genomes. Positional consistency for orthologous genes provides information orthogonal to major sequence features such as the GC content or sequence similarity of marker genes. The positional comparison is therefore useful for identifying large-scale genome rearrangements or gene transfers.

Collaboration today is often done among people from different countries located in different time zones. Even if daily activity patterns are very similar, the displacement of the time of the day, due to the time zone can reduce the possibilities to have a meeting or contact a collaborator. This paper proposes a visualization technique that shows to different users the activity patterns of collaborator in order to improve the awareness in the team. The representation shows several data types in a 24h clock metaphor. The information conveyed discussed in the paper are email, instant messaging, presence at the computer, scheduled activities in a time windows of 24h, which can be extended to 48h.
