Hello I recently updated to the newest version of perspective and I'm glad to see the new "export" functionality being accessible from widget following this PR #2418 :) However, I am interested in using the export > to html functionality from the python API (something like widget.to_html("file.html") Does this functionality exists today ? I'm not finding it in the docs Thanks |

We have plans to add this, in the meantime this logic is easy to replicate ad-hoc, it is just a simple string template - in Python it would look something like this: def to_html(view, version="2.7.1", layout="{}"):
import base64
arrow = view.to_arrow()
html = """
<!DOCTYPE html lang=\"en\">
<html>
<head>
<meta name=\"viewport\" content=\"width=device-width,initial-scale=1,maximum-scale=1,minimum-scale=1,user-scalable=no\"/>

const worker = perspective.worker();
const binary_string = window.atob(window.data.textContent);
const len = binary_string.length;
const bytes = new Uint8Array(len);
for (let i = 0; i < len; i++) {{
bytes[i] = binary_string.charCodeAt(i);
}}
window.viewer.load(worker.table(bytes.buffer));
window.viewer.restore(JSON.parse(window.layout.textContent));

""".format(version, base64.b64encode(arrow), layout)
return html |
