![]() (No worries, in this way, they will still show up when you hover over the connectors. Oh, and let’s also get rid of the arrow markers so they don’t cluster the outlook. In addition, we’ll format the labels to make them better legible. So you can easily include modifications that are specific for your needs. Let’s change their shape to circles and their color to red. An圜hart is a very flexible JS charting library. The city markers can be styled in a straightforward manner. Var series_marker = map.marker(data_marker) Ĭheck out the resulting JS-based connector map with the full code on JSFiddle. Here’s a dataset for our connector map visualization: var dataSet = [ So, our dataset will be an array of objects, where each object is a connector defined by four values: the latitude of the start point, the longitude of the start point, the latitude of the end point, and the longitude of the end point. We will be using the object notation in this tutorial. Here is the list of the cities along the route that will be visualized, with their latitudes and longitudes: Cityįor a connector map, data can be arranged as objects or arrays. In order to get the coordinates of the cities mentioned above, we can use one of multiple coordinate generator tools. In a connector map, the start and end points of each connection line are defined using their latitude and longitude. Let’s visualize one of them, from Xian to Venice, which lied through the cities of Lanzhou, Dunhuang, Qiemo, Hotan, Kashgar, Merv, Tehran, Baghdad, Antioch, and Athens. Third, let’s set data for our JavaScript-based connector map. The JS connector map code will be written here. ![]() We need the Core and Geo Map modules to take care of data visualization in the form of a connector map, geodata for a world map, and the Proj4js library to take care of geographic coordinates. It has connector maps among the supported chart types, a detailed documentation, and a free version. In this tutorial, for illustration, we will be using a JS charting library called An圜hart. The basic approach is quite similar for all, though. Each has pros and cons, so which one to pick always depends on exactly what, where, and how you want. In most cases, you can choose from a wide range of JavaScript charting libraries to handle interactive data visualization on the web. Second, we need to reference all scripts that will be used for data visualization, in the section. Its id attribute is set as “container.” The width and height parameters of the element are 100%, which will ensure the connector map is displayed over the entire screen. In the example above, the block element is. Then, we set a style declaration in a style sheet. ![]() Java 2.1k 351 Repositories An圜hart Public An圜hart is a lightweight and robust JavaScript charting solution with great API and documentation. It runs on API 19+ (Android 4.4) and features dozens of built-in chart types. Right there, we add an HTML block element and assign it a unique identifier. An圜hart Android Chart is an amazing data visualization library for easily creating interactive charts in Android apps. Write some JS code to draw the connector map.įirst of all, where should we put our interactive connector map? Let’s create a basic HTML page.The entire path can be broken down into four fundamental moves: The logic behind creating connector maps with JavaScript is pretty straightforward. Without more ado, let’s get to the connector mapping business! Building a Basic JS Connector Map Here is a preview of how the final JavaScript-based connector map of the tutorial will look. We’ll start with the development of a basic JS connector map in four moves and then make a few tweaks to make it look awesome. Step by step, we will be visualizing a route of the famous ancient Silk Road. In this tutorial, you’ll learn how to quickly create a compelling interactive one using JavaScript. When viewing a preview you can click on "Map reference" button and see the details of the map (bounds, regions, data attached).Connector maps are designed to be ideal for visualizing routes and other links between locations in geospatial data analysis.
