A Python plotting guide for turning tables and multidimensional datasets into charts with a Pandas-style interface. It supports data from Pandas, Polars, Xarray, DuckDB, Dask, and GeoPandas.

Use it to create interactive charts for tabular data, time series, geographic data, and large datasets. It also covers hover details, dimensions, layouts, styling, and statistical plots.

It helps avoid incorrect plotting patterns and makes it easier to choose charts, labels, and interactions that clearly show what the data means.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add holoviz-dev/holoviz-skills --skill hvplot

Clone the repo

git clone --depth 1 https://github.com/holoviz-dev/holoviz-skills

Made for: Claude Code.

Or install holoviz, the plugin that ships this one along with the rest of its 14 skills.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00079	$0.04519
Opus 5.5	$0.00032	$0.01808
Sonnet 5.5	$0.00016	$0.00904
Haiku 4.5	$0.00008	$0.00452

Security

Grade A, and why

hvplot scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 16d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

hvPlot

This skill provides correct patterns and common pitfalls for hvPlot to visualize data interactively.

Before plotting, consider: what story does the data tell? What comparison matters most? Then choose the plot type, encoding, and labels that make that story obvious. For publication-quality figures needing fine-grained control, use HoloViews directly with the Matplotlib backend instead of Bokeh.

Composing Exploratory Plots — layered marks (violin/box/scatter), shared-axis layout for comparison, overlay discipline, faceting around the nested-categorical-axis limit, ordered categoricals, cross-filtering with linked selections
Distilling Explanatory Plots — one-message charts for an audience: takeaway title, gray context + one highlight, direct inline labels, in-place annotation, killing chart junk, assuming no interaction

Lookup

Plotting options by group (axes, geographic, styling, resampling): https://hvplot.holoviz.org/en/docs/latest/ref/plotting_options/{group}.html
Anything else: web-search https://hvplot.holoviz.org/search.html?q=<topic>.

Dependencies

Activate the .hvplot accessor with the appropriate backend import: import hvplot.pandas, hvplot.polars, hvplot.xarray, hvplot.duckdb, or hvplot.dask. Backends like Polars and DuckDB must be installed separately. Optional: datashader for resampling, geoviews or geopandas for geographic data. Prefer the Bokeh backend (default) for interactivity, Matplotlib for static/print output, Plotly as a last resort.

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
