{"version":"1.0","type":"rich","title":"test","description":"This example visualizes the fictional Hogwarts student dataset from the Palmer Penguins-derived template, plotting the distribution of student hobbies across four houses and seven school years. The visualization uses a stacked bar chart, with each bar representing a school year and segments colored by hobby, encoded via the d3-scale-chromatic categorical color scheme. The chart highlights the frequency of each hobby, such as Wizard chess and Potion brewing, across houses and years, emphasizing patterns like the prevalence of Magical creatures in Gryffindor or the concentration of Wizard chess among second-years. The author demonstrates how to parse categorical and quantitative fields—Roll Num as a number, Year as a quantitative axis—and map them to visual channels. The original data is attributed to the Harry Potter fandom and is licensed under MIT.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8a9b88f44b574a679dc7c887f7577875?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
