name	developing-with-holoviz
description	Route to HoloViz sub-skills. Use for ANY task involving interactive plots, dashboards, data apps, reactive parameters, or custom JS/Python components in the HoloViz ecosystem (Panel, hvPlot, HoloViews, Param), including Panel apps that embed Bokeh, Matplotlib, or Plotly figures. A named plotting library (e.g. bokeh) is not a reason to skip this skill.

Developing with HoloViz

This is a routing skill. You MUST use the view tool to read every sub-skill file listed in the table below that matches the task BEFORE writing any code or giving any answer. Do not skip this step!

Instructions

1. Identify which sub-skill(s) apply from the Loading Table below.
2. Use the view tool to read each matching sub-skill file in full.
3. Only after reading the sub-skill file(s), proceed with the task.

For new apps, prefer panel-material-ui over standard Panel templates — it provides modern Material Design components out of the box.

Loading Table

A single request often spans multiple skills. Read ALL that apply. The Panel skill has reference files under developing-with-holoviz/skills/panel/ for specialized topics — read those too when relevant.
