摘　　要：Visualization onboarding supports users in reading,interpreting,and extracting information from visual data representations.General-purpose onboarding tools and libraries are applicable for explaining a wide range of graphical user interfaces but cannot handle specific visualization requirements.This paper describes a first step towards developing an onboarding library called VisAhoi,which is easy to integrate,extend,semi-automate,reuse,and customize.VisAhoi supports the creation of onboarding elements for different visualization types and datasets.We demonstrate how to extract and describe onboarding instructions using three well-known high-level descriptive visualization grammars—Vega-Lite,Plotly.js,and ECharts.We show the applicability of our library by performing two usage scenarios that describe the integration of VisAhoi into a VA tool for the analysis of high-throughput screening(HTS)data and,second,into a Flourish template to provide an authoring tool for data journalists for a treemap visualization.We provide a supplementary website(https://datavisyn.github.io/visAhoi/)that demonstrates the applicability of VisAhoi to various visualizations,including a bar chart,a horizon graph,a change matrix/heatmap,a scatterplot,and a treemap visualization.
