https://gosling-lang.github.io/gos/gallery/bar_chart.html there is no visuals on the website and locally running the code produced the same blank output. Please investigate.

Thank you for submitting an issue! It looks like the resgen server (a data server used in the example) has a certification issue at the moment. If you replace the data with https://server.gosling-lang.org/api/v1/tileset_info/?d=cistrome-multivec (which is a dataset used in our Gosling editor examples), you should be able to see visuals.

data = gos.multivec(
-   url="https://resgen.io/api/v1/tileset_info/?d=UvVPeLHuRDiYA3qwFlm7xQ",
+   url="https://server.gosling-lang.org/api/v1/tileset_info/?d=cistrome-multivec",
    row="sample",
    column="position",
    value="peak",
    categories=["sample 1"],
    binSize=5,
)
