JavaScript/jQuery Vector Map - Bubble Markers

This example demonstrates how you can flag specific locations on the JavaScript VectorMap using markers of the «bubble» type. Marker size depends upon the attribute specified by the dataField property.

Backend API
$(() => { $('#vector-map').dxVectorMap({ layers: [{ dataSource: DevExpress.viz.map.sources.world, hoverEnabled: false, }, { name: 'bubbles', dataSource: markers, elementType: 'bubble', dataField: 'value', minSize: 20, maxSize: 40, sizeGroups: [0, 8000, 10000, 50000], opacity: 0.8, }], tooltip: { enabled: true, customizeTooltip(arg) { if (arg.layer.type === 'marker') { return { text: arg.attribute('tooltip') }; } return null; }, }, legends: [{ source: { layer: 'bubbles', grouping: 'size' }, markerShape: 'circle', customizeText(arg) { return ['< 8000K', '8000K to 10000K', '> 10000K'][arg.index]; }, customizeItems(items) { return items.reverse(); }, }], bounds: [-180, 85, 180, -60], }); });
