shinyCircos-V2.0: Leveraging the creation of Circos plot with enhanced usability and advanced features

We previously developed shinyCircos, an interactive web application for creating Circos diagrams, which has been widely recognized for its graphical user interface and ease of use. Here, we introduce shinyCircos-V2.0, an upgraded version of shinyCircos that includes a new user interface with enhanced usability and many new features for creating advanced Circos plots. To help users get started with shinyCircos-V2.0, we provide detailed tutorials and example input data sets. The application is available online at and , or can be installed locally using the source code deposited in GitHub (). We developed a web application called shinyCircos-V2.0 for creating Circos plots. The process of creating a Circos plot with shinyCircos-V2.0 involves three simple steps: uploading the input data, setting the plotting parameters, and generating the Circos plot. Our application offers a wide range of plotting parameters that can be used to enhance the appearance of the resulting Circos plot. Overall, shinyCircos-V2.0 simplifies the creation of Circos plots and provides researchers with a powerful tool for data visualization.Highlightsimage We presented a web application shinyCircos-V2.0 for creation of a Circos plot.shinyCircos-V2.0 is an upgraded version of shinyCircos with a more user-friendly interface and many new features.Detailed tutorials and example input data sets are provided to enhance the usability of shinyCircos-V2.0.
