{"version":"1.0","type":"rich","title":"Marks and Channels AE","description":"The visualization displays eye-tracking data from 86 undergraduate students solving math problems, focusing on average fixation duration and response patterns. It shows a simple bar chart where each rectangle’s height represents a data value, with white lines marking the minimum threshold. The example uses d3-selection and d3’s join pattern to render twelve small multiples of the same chart, each built with a reusable `length` function that draws rect and line elements. The fixed dataset contains five pairs of numbers, and the charts are laid out as separate SVG elements with a cadetblue background.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
