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 self-contained chart-type recipes spanning financial, statistical, map, table, and 3D categories, all written in the page's existing python demo exec style.

• The Candlestick example fetches a remote CSV at module level, contradicting the PR's own quality note and risking page-load failures on network errors.
• The funnel_chart() function name breaks the plotly_* prefix convention, and the pre-existing "3D graphing example" section is now structurally orphaned from the new "## 3D Charts" group.

Confidence Score: 3/5

Safe to merge after fixing the Candlestick remote-fetch; the rest of the content is docs-only and self-contained.

The Candlestick example calls pd.read_csv against a remote GitHub URL at module/import level, meaning any network hiccup during a docs build will cause an unhandled exception that breaks the page. This directly contradicts the PR's own stated quality bar. The remaining 13 examples are clean and self-contained.

docs/library/graphing/other-charts/plotly.md — specifically the Candlestick code block around line 271.

Important Files Changed

Filename	Overview
docs/library/graphing/other-charts/plotly.md	Adds 14 new chart-type recipes across six new sections; Candlestick example fetches a remote CSV at module level, contradicting the PR's stated quality approach and risking build failures; minor naming and page-structure inconsistencies also present.

   Existing "3D graphing example" section is now orphaned from the new "## 3D Charts" group

   The pre-existing "3D graphing example" section (the Mount Bruno surface plot) sits between the new Financial/Statistical/Maps/Tables sections and the new "## 3D Charts" group, so there are now two separate 3D areas on the page. Readers looking for 3D chart examples will find an isolated one mid-page and a curated group at the bottom, which feels fragmented. Consider moving the surface-plot example inside the "## 3D Charts" section, or renaming the existing header to "3D Surface Plot" and folding it into the new group.

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.

Remote CSV fetch at module level contradicts PR's stated approach

The PR description explicitly states that "source snippets that fetched remote CSVs/JSON at import time were deliberately dropped or replaced" — yet the Candlestick example still calls pd.read_csv("https://raw.githubusercontent.com/...") at module level. Because python demo exec blocks run at import time, a network failure, rate limit, or GitHub unavailability will cause an unhandled exception that breaks the entire docs page. Replace with a small inline DataFrame using hardcoded OHLC values, matching the self-contained pattern used by all other new examples in this PR.

Naming inconsistency: funnel_chart breaks the plotly_* prefix convention

Every other chart function in the "Plotly Express Chart Types" section uses the plotly_ prefix (e.g. plotly_bar_chart, plotly_scatter_plot, plotly_box_plot). funnel_chart is the only one that doesn't, which will look inconsistent to readers copying the pattern.

Suggested change

	def funnel_chart():
	return rx.center(rx.plotly(data=funnel_fig))
	def plotly_funnel_chart():
	return rx.center(rx.plotly(data=funnel_fig))
