We knew we wanted a tooltip text to show restaurant name/stars/no. reviews on the lowest level, but as the map zoomed out and clustered, we weren’t sure what information would be most useful to the viewer. Yamini and Amrut created a dynamic tooltip that would show aggregate data when zoomed out. Users also felt confused by circle sizing when zoomed out and wanted a legend. Thus, Jenny created a dynamic legend that would update with zooming. This was challenging in d3 as the legend values are dynamically edited using mutables according to both the clusters and the zoom level. To scale the circle sizes, heuristics were created in the generateGrades function. Another challenge was the combination of two different libraries, which made it difficult to ensure the legend was updated upon zoom. The legend also blocked the graph when zoomed out at high levels, so Amrut and Jenny made the design choice to use a divIcon to show the cluster size instead for those situations. Users praised the color coordinated circles and drop down menu UI, which Amrut made, as feeling intuitive. 33:Tcc8,apply = { const featureGroup = L.featureGroup().addTo(map); const nodes = fd_grp_review_filtered.map(d => createNode(map.latLngToLayerPoint([d.latitude, d.longitude]), d.review_count, d.stars, d.name)); // init the cluster ! const cluster = mc .cluster() .nodes(nodes) .on("tick", ticked); // bind to zoom events map.on('zoomend', zoomend); // map.on('move', zoomend); // on d3-marker-cluster update function ticked() { const current = this.nodes(); const filtered = current.filter(d => d.r != 0); // filter out dead nodes //https://bl.ocks.org/Andrew-Reid/21ff4b57267fa91dacc57ef1ccb7afb3 // heuristic ? if (filtered.length !== current.length) { this.nodes(filtered); // faster iterations featureGroup.clearLayers(); // remove old layers mutable max_area = 0; mutable radii = []; let circleMarkers = []; filtered.forEach(function(c){ const mark = createMarker(map.layerPointToLatLng([c.x, c.y]), c); mark.addTo(featureGroup); circleMarkers.push(mark); mutable max_area = Math.max(mutable max_area, c.a); const area = radius_selector.match('Restaurants') ? c.a/30 : c.a*4; if(map.getZoom() < 8 && circleMarkers.length<15){ if(radius_selector.match('Restaurants') && area > 50){ var myIcon = L.divIcon({ className: 'my-div-icon', html: ` ${String(area)} `, iconAnchor: [12, 7] }); L.marker(map.layerPointToLatLng([c.x, c.y-c.r]), { icon: myIcon }).addTo(featureGroup); } else if (area>1000){ var myIcon = L.divIcon({ className: 'my-div-icon', html: ` ${String(area)} `, iconAnchor: [20, 7] }); L.marker(map.layerPointToLatLng([c.x, c.y-c.r]), { icon: myIcon }).addTo(featureGroup); } } }); const markersInBound = filterByBound(circleMarkers); const radiiArr = [...new Set(markersInBound.map(m => m.getRadius()))]; const radii = generateGrades(d3.min(radiiArr), d3.max(radiiArr)); mutable radii = radii.map(r => Number(r)); } legend.addTo(map); } // when we zoom function zoomend() { cluster.stop(); // stop the cluster featureGroup.clearLayers(); // remove old layers // recompute the position of the nodes depending on actual zoom const data = cluster .nodes( fd_grp_review_filtered.map(d => createNode(map.latLngToLayerPoint([d.latitude, d.longitude]), d.review_count, d.stars, d.name)) ) .alpha(1); // update the data cluster.restart(); // start the clusterer } // when we throw the cell away invalidation.then(() => { cluster.stop(); // stop the cluster :) map.off('zoomend', zoomend); // unbind events featureGroup.remove(); // remove the displayed markers }); return md`~~~observable "Important" // this cell adds markers to cluster and cluster to map ~~~`; }34:T565,legend.onAdd = function (map) { var div = L.DomUtil.create('div', 'info legend'), grades = [...new Set (radii.map(radius => Number(radius.toFixed(2))))].sort((a, b) => a - b), // radii = grades.map(d => Math.round(Math.sqrt(d/Math.PI))), labels = radius_selector.match('Restaurants') ?
