How is D3 used to draw a map?
A GeoJSON file is uploaded and D3 is used to project the geographic data and draw it on a Canvas element: D3’s approach differs from so-called raster methods like Leaflet and Google Maps. These map features are pre-rendered as image tiles and loaded from a web server and assembled in the browser to form a map.
How are raster maps rendered in depth in D3?
Typically, D3 requests vector geographic information in the form of GeoJSON and renders it to SVG or Canvas in the browser. Raster maps are often more like traditional printed maps in that many details (for example, place names, roads, rivers, etc.) can be displayed without affecting performance.
When does the wave height reach its maximum at D3?
When true, the wave height reaches its maximum at 50% fill and minimum at 0% and 100% fill. This helps prevent the wave from making the wave circle appear fully filled or empty when it is close to its minimum or maximum fill. waveAnimate: true, // Controls whether the wave is scrolling or static.
Can a D3 dash indicator be rendered using SVG?
D3.js often renders data using SVG because SVG is a valid HTML tag and can be easily added to or removed from the DOM of a web page. In fact, if you look closely at the implementation of the node-RED flag, it also implemented the flag using SVG. By no better name, I called my project D3 Dashboard Gauge.
What are the characteristics of a liquid fill indicator?
Configurable features include: Modifiable minimum/maximum values. All colors. Thickness of the outer circle. Space between the outer circle and the inner padding area. Wave height. Wave speed. Wave count. Wave rise time. Activation/deactivation of the wave height scale. Reduce the height of the wave near the minimum/maximum values so that the wave does not make the fill area appear fully filled or fully empty.
What does D3.js mean in JavaScript?
D3.js or simply D3, stands for Data Driven Documents, is a JavaScript library for producing dynamic and interactive data visualization in web browsers using SVG, HTML, and CSS standards. D3.js often renders data using SVG because SVG is a valid HTML tag and can be easily added to or removed from the DOM of a web page.
