docs: expand the Plotly page with 14 chart-type recipes

[amsraman]

What

Second batch of upstreaming Reflex Build's AI-builder knowledge base into the official docs (first: #6775). This one converts the Plotly chart recipes into 14 new sections on docs/library/graphing/other-charts/plotly.md:

• Plotly Express section gains: Bubble Chart, Gantt Chart (px.timeline), Sunburst Chart, Funnel Chart
• New Financial Charts group: Candlestick, Waterfall, Bullet (go.Indicator)
• New Statistical Charts group: Continuous Error Bands (reversed-bound fill="toself" technique)
• New Maps group: Geo Map (go.Scattergeo + update_geos), Scatter Map (px.scatter_map)
• New Tables and Diagrams group: go.Table, Sankey Diagram
• New 3D Charts group: 3D Scatter (px.scatter_3d), 3D Axis configuration (go.Mesh3d + scene axes)

Quality notes

• Every new example is a self-contained python demo exec block in the page's existing style (module-level figure + def *_chart()); all blocks on the page were exec-verified (the only non-running one is the pre-existing surface-plot example that reads a docs-site-local CSV).
• Source snippets that fetched remote CSVs/JSON at import time, required geopandas, or used deprecated APIs (ff.create_gantt) were deliberately dropped or replaced with their modern equivalents.
• One source snippet mislabeled its data ("The Great Recession" over 2016 AAPL data) — retitled.

If the maintainers would rather see the new groups split onto separate pages (e.g. plotly-maps.md), happy to restructure — one page keeps the diff reviewable for now.

Greptile Summary

This PR expands the Plotly docs page with 14 new self-contained chart-type recipes grouped into six new sections (Financial Charts, Statistical Charts, Maps, Tables and Diagrams, 3D Charts, plus four new Plotly Express subsections). All examples use inline data — previous review feedback about a remote CSV fetch in the Candlestick example and the funnel_chart naming inconsistency have both been addressed in this revision.

• 14 new recipes added covering Bubble, Gantt, Sunburst, Funnel, Candlestick, Waterfall, Bullet, Continuous Error Bands, Geo Map, Scatter Map, Table, Sankey, 3D Scatter, and 3D Axis charts — each as a self-contained python demo exec block with no network dependencies.
• Minor naming inconsistency remains within the new sections: plotly_table and plotly_sankey_diagram carry the plotly_ prefix while the other new section functions (candlestick_chart, waterfall_chart, etc.) do not.

Confidence Score: 5/5

Safe to merge — all changes are documentation additions with no runtime or application logic changes.

The change is purely additive documentation: 14 new self-contained code examples with hardcoded inline data. Previously raised issues (remote network fetch at module level, funnel naming) are fixed. No application code is touched.

No files require special attention; the single changed file is documentation only.

Important Files Changed

Avoid fetching remote data during docs render

This python demo exec block is executed while the docs page is rendered (_render_demo runs _exec_code for these fences in docs/app/reflex_docs/docgen_pipeline.py), so reading the CSV from GitHub here makes the Plotly docs page depend on external network availability and latency. In offline/local builds or transient GitHub failures this single example prevents the page from rendering; use a small inline DataFrame or a checked-in docs data file instead.
