This example shows how to merge external attribute data from CSV or TSV files into a GeoJSON FeatureCollection, using a property or feature ID as the join key. It accepts multiple property files and can transform selected fields, including converting strings to numbers with a leading plus sign. The script runs on Node.js and uses the `optimist` library for command-line parsing, the `dsv` library for delimited file parsing, and standard `fs` and `JSON` modules for file I/O and serialization. The output is written either to a specified file or to standard output.

object loop

This example converts GeoJSON data containing town health center information into CSV files, one per feature collection in the dataset. The code iterates through each array in the `data` variable, extracts the properties from each feature, and uses `jsonToCSV` to create a comma-separated representation with headers. It then triggers a browser download via the `downloadCSV` function, setting the `href` and `download` attributes on the hidden anchor element. The process relies on JavaScript’s `Object.keys`, `JSON.stringify`, and array mapping, while D3 is only imported but not actively used in the visualization logic.

GeoJSON Transforms

This example demonstrates how GeoJSON geometry types can be transformed into simplified or filtered representations by applying custom point, line, and polygon handlers. It builds on the D3 geo module’s type dispatch system, explicitly defining default handlers for Feature, FeatureCollection, and GeometryCollection objects alongside primitive geometries. The code uses d3_geo_type and d3_noop to create a reusable translator, showing how to override or extend processing for each GeoJSON type. The rendering approach is not shown, focusing solely on the data-transformation pipeline.

Clean Up for Natural Earth GeoJSON

This example presents a command-line Node.js script for cleaning Natural Earth GeoJSON data. It reads a GeoJSON collection from standard input and outputs a simplified version, retaining only the `name` property and an `id` derived from either the `ISO_A3` or `FIPS` code. The script uses `JSON.parse` and `JSON.stringify` for data processing, and it rounds all coordinate values to six decimal places via a custom `round` function applied to `Polygon`, `MultiPolygon`, and `LineString` geometries. The process logs warnings for invalid country codes.

Single Feature

This example shows a single GeoJSON point feature derived from a biodiversity occurrence record, with its geographic coordinates and a linked identifier exposed as properties. The code constructs the feature by first querying the Global Biodiversity Information Facility (GBIF) API with a specific occurrence ID, then parsing the returned JSON to extract the latitude, longitude, and record identifier. Using the XQuery `map` syntax, it assembles a standard GeoJSON object with a Point geometry and a `name` property. The visualization relies on HTTP retrieval via `fetch:text` and JSON parsing via `fn:parse-json`, with no external charting library; the output is intended for a map renderer that consumes GeoJSON.

Creating a GeoJSON file with a square 100x100 in Power Query

This example generates a GeoJSON FeatureCollection containing a 100x100 grid of square polygons entirely within Power Query. It demonstrates constructing polygon coordinates for each cell using nested list functions and the `List.Accumulate` API to iterate over rows and columns. Each feature carries an `ID` property and a `Polygon` geometry with a closed ring of five coordinate pairs. The final `Json.FromValue` call serializes the entire nested list structure into valid GeoJSON, producing a downloadable file without external GIS tools. The code visibly uses Power Query’s `let` and `in` syntax, list literals, and the `Json` functions.

Let's make a Map with simplified code!

This example shows a world map rendered as SVG paths, with countries filled in light green and the ocean sphere in blue. The code uses D3 v5's `geoNaturalEarth1` projection and `geoPath` to convert geographic data into SVG path strings, while TopoJSON's `feature` method transforms the TopoJSON world-atlas dataset into GeoJSON features for rendering. A data join appends one path per country, and the map is loaded asynchronously via `d3.json` from a remote unpkg URL.

GeoJSON Experiments

This example displays geographic data on an interactive Mapbox map, using the Mapbox.js library and a full-screen map div. It fetches GeoJSON data from a CouchDB view via a jQuery `$.getJSON` call, then loads the returned feature collection into the map’s `featureLayer` with `setGeoJSON`. The map is initialized with `L.mapbox.map` and centered on coordinates (10.1, 125.6) at zoom level 5, showing how dynamic GeoJSON can be rendered on a tiled basemap.

Custom Cartesian Projection

This example displays a set of land parcel polygons from a GeoJSON file, drawn as light gray shapes with black outlines on an SVG canvas. It creates a custom Cartesian projection by implementing a `d3.geoTransform` that maps raw coordinates through two `d3.scaleLinear` scales for the x and y axes. The resulting transform feeds into a `d3.geoPath` generator, which renders the geographic features using the projected coordinates, bypassing standard geographic projections.
