🗺 A Javascript API library built upon SVG World Map JS and Chart.js for time series data visualization.

Attention: This project is under development and currently in early alpha phase. Detailed installation and integration with more examples will follow soon.

This API provides a quick integration for the projection of time series data sets on world maps. Use this API library for Choropleth Maps for Data Visualization of scientific and statistical data, or as Interactive Map for your article, paper, website or app.

The underlying SVG World Map JS is just a small library for fast and simple data projection. If you need more advanced features for data visualization and SVGs, have a look at d3js.


Effective decision-making for crisis mitigation increasingly relies on visualisation of large amounts of data. While interactive dashboards are more informative than static visualisations, their development is far more time-demanding and requires a range of technical and financial capabilities. There are few open-source libraries available, which is blocking contributions from low-resource environments and impeding rapid crisis responses. To address these limitations, we present SeismographAPI, an open-source library for visualising temporal-spatial crisis data on the country- and sub-country-level in two use cases — Conflict Prediction Map and COVID-19 Monitoring Map. The library will provide easy-to-use data connectors, broad functionality, clear documentation and run time-efficiency.

Installation & Basic Setup

» Demo: Basics

Attention: As this project is currently under development, the installation may change in future versions.

Add the /src/ and /lib/ folders to your project, include seismographAPI.js in your HTML document, add a data source, then call the library:

<script src="src/seismographAPI.js"></script>
    var myDataPath = '';
    seismographAPI({ dataPath: myDataPath });

This will load the SVG map and Chart.js via Javascript injection and initialize the library.
So far for the basic setup.

Custom Options

» Demo: World Bank Data Example
» Demo: Conflict prediction interpretability map
  • All default options can be overruled by passing an object of custom options
  • Set dataPath to your data source. This is the only parameter which is mandatory!
  • showCountryList, showDetails, showTimeline and darkMode will toggle these functions
  • svgMapOptions are passed through, please see SVG World Map JS for more information
  • chartDetailOptions and chartTimelineOptions are passed through, please see Chart.js for more information
// Default options
var options = {
    infoTitle: 'SeismographAPI', // Map info title
    dataPath: '', // Point to data path, e.g. 'data/'
    showCountryList: true, // Show or hide country list
    showDetails: true, // Show or hide details
    showTimeline: true, // Show or hide timeline
    darkMode: false, // Toggle dark mode
    svgMapOptions: {}, // SVG World Map options
    chartDetailOptions: {}, // Chart.js options
    chartTimelineOptions: {}, // Chart.js options

The custom options are passed as a parameter list to the map at startup. You can either hand them over as an object similar to the one above:


Or as inline parameter:

seismographAPI({ dataPath: 'data/' });
