This example builds an interactive map of Zurich and draws transit routes from a GeoJSON file using D3 v5. It demonstrates a modular map component that initializes a Mercator projection and sets up SVG rendering for geographic paths. The code explores loading GeoJSON data asynchronously via `d3.json` and a promise-based `.then()` callback, while a commented data manager module shows an alternative approach using `d3.dispatch` for custom events. Route data comes from the D3Edge GitHub repository, and the visualization uses `d3.geo.mercator` and `d3.geo.path` for projection and path generation.

d3Edge_V5-dataLoading-v0.3

This example demonstrates a custom data-loading module for D3 v5 that manages asynchronous CSV and GeoJSON requests through a dispatch system. It shows how to load Zurich transit delay data from a remote CSV file, clean the rows by parsing timestamps and coordinates, and expose the processed dataset via a public API. The code uses `d3.csv`, `d3.json`, and a `d3.dispatch` event bus to signal loading progress and readiness, with a placeholder page indicating when data is available for console inspection.

d3Edge_V5-dataLoading-v0.4

This example demonstrates a modular data-loading system for D3.js v5, built around a custom dispatch event manager. It loads a CSV file of Zurich transit delay data and a separate TopoJSON geographic file, applying a cleaning function to parse timestamps and coordinates. The code uses asynchronous `d3.csv` and `d3.json` loading with custom `dataLoading`, `dataReady`, and `geoReady` events, and exposes methods like `getCleanedData()` for console inspection. The visualization itself remains a placeholder, showing a loading message and instructions while the data pipeline runs.

D3 test

This example visualizes a historical route from a GeoJSON file, displaying daily segments as dashed black polylines over a light blue graticule-filled map. The code uses D3 v5 with an SVG rendering approach and a Mercator projection configured via `d3.geoMercator()`. It loads coastline and route data with `d3.json()`, then binds the features to SVG paths using `d3.geoPath()`. The graticule is generated with `d3.geoGraticule()`. The visualization clearly shows the path’s progression across the mapped region, with each day’s travel distinguished by styling properties like stroke dasharray.

Fork of d3Edge_V5-dataLoading-v0.1

This example demonstrates a custom data-loading module for D3.js v5, using a dispatch-based event system to manage asynchronous CSV and GeoJSON data. The module, defined as `d3Edge.dataManager`, loads Zurich transit delay data via `d3.csv`, applies a cleaning function to parse timestamps with `d3.time.format` and convert coordinates, and then dispatches a readiness event. The accompanying HTML page shows a "loading" message until the data is prepared, after which users can inspect the cleaned data in the console.

Let's make a map with D3.js!

This example displays a choropleth map of geographic features rendered as SVG paths. It uses D3.js v5 to load the GeoJSON data, apply a Mercator projection with `d3.geoMercator`, and generate the path data via `d3.geoPath`. The TopoJSON library converts the datasource into GeoJSON features using `feature()`, while `d3.json` fetches the remote file before appending each path to the SVG canvas.

Let's make a map with D3.js!

This example demonstrates how to create a simple world map using D3.js v5 and TopoJSON. It loads geographic data from a remote JSON file and renders each country as an SVG path using `d3.geoMercator` for the projection and `d3.geoPath` to generate the path data. The map is drawn onto a static SVG canvas with no interaction or animation. The code relies on the `json` function from D3’s fetch module and the `feature` method from TopoJSON to convert the raw data into GeoJSON features.

Let's make a map with D3.js!

This example shows a simple world map rendered with D3.js, displaying geographic features as green filled paths with black borders against a blue background. The visualization loads GeoJSON data from a remote GitHub URL using `json()` and applies `geoPath()` from the d3-geo module to generate the SVG path data. With topojson-client’s `feature()` method, the code binds the geographic features to `path` elements in an SVG canvas via `selectAll()`. The map is static, with styling defined in CSS, and serves as a basic introduction to mapping with D3 v5.

Let's make a map with D3.js!

This example loads a GeoJSON file of world country boundaries from a remote URL and logs the parsed data structure to the browser console, preparing for map visualization. The SVG canvas is set to 960 by 500 pixels, and the page uses D3 v5 along with TopoJSON v3 to handle geographic data. The code imports `select` and `json` from D3 and `feature` from TopoJSON, though the actual map rendering with `d3.geoPath` is not yet implemented, leaving the visualization incomplete at this stage.
