  "account": "Structural variants (SVs) are significant genomic alterations that can disrupt essential functional and regulatory elements, resulting in genetic disorders in humans and playing crucial roles in plants' domestication, disease resistance, and traits. These SVs occur across various populations of individuals and are leveraged in association studies, utilizing extensive datasets encompassing thousands of genomic loci. To facilitate a deeper understanding of these SVs, visualization tools are employed, aiding in the comprehension of their genomic distribution, identification of patterns within affected or phenotypic clusters, and assessment of their proximity to other regions of interest. Numerous tools currently exist for SV visualization, such as linear genome browsers and graph-based methods; however, many lack intuitive or scalable representations of SVs across expansive populations. In response to this challenge, the authors introduce SVPopEx, an interactive tool designed for population-wide visualization and exploration of SVs. SVPopEx offers an innovative and intuitive depiction of insertions, deletions, inversions, duplications, and translocations within a linear genome-style browser. The tool also incorporates novel features to facilitate comparisons across genomes within user-defined regions, such as rendering SVs based on one or more samples and visualizing haplotypes. The authors substantiate the efficacy of SVPopEx using datasets from Schistosoma mansoni and Lens culinaris. Additionally, a task-based evaluation involving SVPopEx and two other linear genome browsers reveals that SVPopEx outperforms the others in two key aspects: delivering a clear representation of SVs present and enabling effective comparisons across genomes.",
