fix: make chart iframes responsive and extract iframe helper
Nolan Zandi+1: Claude Sonnet 4.6
b9b70e3
Replace 10 copies of hardcoded pio.write_html + 1000px iframe string
with a single _write_chart(fig, path, url) helper that writes the file
with config={'responsive':True} and returns width:100% / min-width:400px
iframe HTML. Charts now fill the available chat width on any screen size
and redraw when the container resizes instead of overflowing at 1000px.

feat: add rolling stats, K-Means clustering, and hypothesis testing
Nolan Zandi+1: Claude Sonnet 4.6

- Add rolling_stats_func: overlays rolling mean/std/min/max on a time
series using plotly.graph_objects; supports optional category grouping
- Add kmeans_clustering_func: StandardScaler + KMeans (sklearn), scatter
plot coloured by cluster, centroid summary table
- Add hypothesis_test_func: independent/one-sample t-test (scipy) and
chi-square test of independence; returns styled HTML results table
- Register all three in tool schemas, __init__.py, available_functions,
and system message; add scipy and scikit-learn to requirements.txt
- Refactor chart_tools.py: extract _LAYOUT_PARAM and _TRACE_STYLE_PARAM
constants to eliminate ~8x copy-paste; remove layout from required
arrays on line/bar/pie; fix hardcoded 'SQLite' references; standardise
all tool descriptions to consistent what/when/returns format
- Refactor stats_tools.py: same description standardisation
- Shorten tools_desc in system message from 13 lines to 2 sentences
(LLM already receives full schema descriptions…
feat: add box plot, correlation heatmap, and descriptive statistics
Nolan Zandi+1: Claude Sonnet 4.6

New analysis functions:
- box_chart_generation_func: distribution and outlier visualisation,
optional x-axis grouping and colour category (px.box)
- correlation_heatmap_func: pairwise Pearson correlation heatmap for
numeric columns using RdBu_r scale (px.imshow); defaults to all
numeric columns if none specified
- descriptive_stats_func: inline summary statistics table (count, mean,
std, min, 25/50/75%, max) styled to match the app theme
Supporting changes:
- Tool schemas added to chart_tools.py and stats_tools.py
- All three functions exported from functions/__init__.py
- All three wired into available_functions in chatbot_func
- system_message refactored: removed repetition across 4 data-source
variants via shared tools_desc string; fixed longstanding bug where
bar_chart_generation_func was referred to as line_chart_generation_func
in the doc_db and graphql system prompts

fix: replace LFS-tracked CSV with a plain 100K-row sample
Nolan Zandi+1: Claude Sonnet 4.6

LFS was silently serving the pointer file to HF Spaces instead of the
actual data, leaving the online_retail_data.csv unqueryable. Root cause:
HF Spaces does not reliably pull LFS objects for Space repos.
Changes:
- Replace 541K-row 45MB CSV with a random 100K-row 8.56MB sample;
retains full column set and date range, sufficient for all demos
- Remove samples/online_retail_data.csv from LFS tracking in .gitattributes
- Clean up historical-file-specific LFS entries from .gitattributes added
by the earlier lfs migrate (data_file.zip, data_source.db, etc.) since
those files no longer exist in the tree
- Also includes: table_generation_func now renders inline HTML in the
chat message instead of an iframe, adapting naturally to any screen width

feat: user-supplied API keys, model selector, and Anthropic support
Nolan Zandi+1: Claude Sonnet 4.6

- Replace hardwired OpenAI key with a per-session API key form at the top
of the UI; key is stored in memory only and cleared on page unload
- Add model dropdown that dynamically switches between OpenAI and Anthropic
model lists based on detected key prefix (sk-ant- vs sk-)
- Add anthropic-haystack dependency for AnthropicChatGenerator support
- Refactor tools/chart_tools.py, tools/stats_tools.py, and tools/tools.py
to use Haystack's provider-agnostic Tool class instead of raw OpenAI-format
dicts, enabling tool calling to work with both OpenAI and Anthropic models
- Fix invalid JSON Schema (items field on non-array properties) in tool
parameter definitions for stricter Anthropic compatibility
- Pass tools via tools= parameter to chat_generator.run() rather than
generation_kwargs so both generators handle format conversion natively
