    Example session with this skill installed

    Create a choropleth map of Germany's states (admin1) using the population data in stats.csv. Use a blue color scale and include a legend titled 'Population 2023'.

    • Generated the data export

    I have generated a choropleth map of Germany's 16 federal states using the Highcharts countries/de/de-all base map. The population data from stats.csv was joined via ISO 3166-2 codes.

    Germany Population Map (SVG)

# Generated using recolor_choropleth.py
# Source: Highcharts admin1 - Germany
# Palette: Blues (sequential)

import cairosvg

# The resulting SVG 'germany_population.svg' contains:
# - CSS-styled paths for all 16 states
# - A dynamic legend with 5 quantiles
# - Title: "Population by State"
# - Subtitle: "Germany, 2023 Data"

# To export a high-res version:
cairosvg.svg2png(url="germany_population.svg", write_to="germany_preview.png", scale=2.0)

    Next steps

    1. Open germany_population.svg in any browser or vector editor to verify the color scales.
    2. Check regions-index.json if you need to map additional data to specific state IDs.
    3. Modify style.json and re-run the recolor script if you need to adjust font families or stroke weights.

    About this skill

    The problem

    Static map images are difficult to update and scale without losing quality. Developers often struggle to bridge the gap between raw GeoJSON/Shapefile data and production-ready, styled SVG visualizations.

    What it does

    • Generates editable SVG maps from Highcharts public data or custom GeoJSON/TopoJSON sources.
    • Creates data-driven choropleths with automatic numeric color scales or categorical swatches.
    • Overlays custom boundaries, historical borders, routes, and point labels onto base maps.
    • Joins CSV or JSON datasets with geographic features using automated ID matching and crosswalk generation.
    • Produces high-resolution PNG previews for visual verification of legends, titles, and data alignment.

    Frameworks & tools

    Python (NumPy, CairoSVG, GeoPandas, Shapely), Highcharts Map API, and Node.js (optional).

    Why this beats prompting it yourself

    Generic LLM prompts often hallucinate coordinates or produce malformed SVG code. This skill uses a systematic pipeline of Python scripts to ensure geometric precision, consistent coordinate transformations, and valid XML output that remains fully editable in design tools.

    Use cases

    • Visualizing regional sales performance or demographic data across specific administrative levels.
    • Creating historical maps with custom boundary overlays on top of modern geographic references.
    • Building reusable map assets for dashboards that require specific brand styling and custom legends.
    • Mapping service areas or logistics routes using real-world river and coastal geometry.

    Known limitations

    Requires local Python environment with CairoSVG for preview rendering. Shapefiles must be converted to GeoJSON before processing.
