This demo uses the Web Speech API to drive a CartoDB map visualization. It listens for spoken words, converts them to text, and submits the transcribed phrase as a search query through the cartodb.js search overlay. The map renders a CartoDB-hosted dataset, and after each utterance, the speech recognition restarts to allow continuous voice-controlled searching. The code relies on `webkitSpeechRecognition` for speech-to-text and the CartoDB `createVis` function to display the map layer.

DataKind Workshop | Demo

This demo embeds a CartoDB map visualization centered on global coordinates, displaying geographic data points as an interactive web map. The iframe loads a published CartoDB visualization with pan and zoom controls enabled, while hiding search, layer selection, and legends for a clean presentation. The underlying map uses CartoDB’s tile-based rendering to show spatial patterns, with the page’s HTML and CSS ensuring the map fills the entire viewport. The code relies on the CartoDB embed API and standard iframe integration rather than custom JavaScript libraries.

This visualization displays a map rendered with CartoDB, showing geographic data from a hosted visualization. The page loads a full-screen map using the CartoDB.js library, which initializes the map via `cartodb.createVis` and connects to a remote visualization URL. The map itself is embedded in a fixed-size `<div>` element and relies on CartoDB’s built-in rendering and tile services to draw the geographic layers. The code does not include custom data processing or interaction logic; it simply leverages the CartoDB API to present the pre-configured map.

CartoDB Workshop | CartoDB.js

This example uses CartoDB.js to display an interactive map inside a full-screen div. The code initializes a map with a single custom overlay button labeled “Do Something,” which sits in the top-right corner and changes its background on hover. The map itself is rendered using the CartoDB library’s tile layers, while the button is styled with the included cartodb-infobox CSS class. The JavaScript structure defines a main function tied to the window load event, though no map layers or data sources are explicitly loaded in the provided snippet.

Easy example | CartoDB.js

This example shows a full-screen interactive map that renders a dataset called "untitled_table_5" with custom CartoCSS styling. The map displays points, lines, and polygons in a red color scheme with white outlines, and includes tooltips triggered by interactivity on the `cartodb_id` field. The code uses the CartoDB.js library version 3, specifically `cartodb.createVis`, which loads the visualization from a JSON configuration object. The base map is provided by OpenStreetMap tiles via Leaflet, while the geographic data is queried from a CartoDB table using SQL and styled with CartoCSS rules for each geometry type.

Easy example | CartoDB.js

This example loads a CartoDB-hosted map visualization into a full-screen `<div id="map">` using the CartoDB.js library. It calls `cartodb.createVis` with a specific `viz.json` URL, setting initial center coordinates at latitude 0, longitude 0, zoom level 2, and disabling the time slider. The map renders the visualization’s default layers and styling from the referenced CartoDB account. The page includes the CartoDB CSS and JavaScript files from `libs.cartocdn.com`, and any loading errors are logged to the console.

This example presents a promotional slideshow for CartoDB, a cloud-based mapping and data visualization platform. The presentation uses D3.js to animate text bullet points and an interactive map visualization, showcasing features like drag-and-drop data importing, real-time dashboards, and GIS analysis through PostGIS. The map rendering employs d3.geoPath to draw geographic boundaries, while the slideshow transitions through sections covering web development integration, team collaboration, and high-performance data processing on scalable infrastructure.

Leaflet example | CartoDB.js

This example combines CartoDB.js with Leaflet to display a choropleth-style map of urban areas, overlaying vector polygons from a CartoDB SQL query. The map uses a Stamen toner tile layer as the base, with a CartoDB visualization layer added via `cartodb.createLayer`. The code enables hover interactions on the sublayer, showing a popup with the `area_sqkm` attribute, and separately renders simplified GeoJSON from the `ne_50m_urban_areas` table using `L.geoJson`. Mouseover events highlight polygons by changing their stroke color to red, while mouseout resets the style.

This example demonstrates how to map and animate earthquake data from the USGS CSV feed using CartoDB’s mapping tools. It shows temporal earthquake occurrences through an interactive map, with points updating over time. The code relies on CartoDB’s SQL API and JavaScript library for layer management, alongside D3.js for data-driven visualizations. It also integrates Chart.js for supplementary graphs and uses dynamic styling via CartoDB’s tile rendering. The visualization highlights both spatial distribution and time-based animation of seismic events.
