{"version":"1.0","type":"rich","title":"Custom web extension","description":"This example demonstrates a custom web extension that extracts numeric values from specific table cells and injects them into a new visualization table with highlighted yellow data areas. The code uses native DOM APIs such as `document.getElementsByClassName`, `createElement`, and `appendChild` to manipulate the HTML structure. It also parses an XML manifest describing the extension’s parameters using `DOMParser` or the ActiveX `XMLDOM` object, outputting the parameter caption and description via `document.write`. The visualization logic itself remains mostly unimplemented, with initialization and callback functions defined but not executed.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4525395e21364e9c93db1b51b0c73090?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
