d3.js - How to add filters effects to Svg in d3 - 


<svg viewbox = "0 0 1100 400" version = "1.1">     <desc>         filter example     </desc>     <filter id = "i1">         <fegaussianblur in = "sourcealpha" stddeviation = "4" result = "blur1"/>         <fespecularlighting result = "specout" in = "blur1" specularexponent = "20" lighting-color = "#bbbbbb">             <fepointlight x = "50" y = "100" z = "200"/>         </fespecularlighting>         <fecomposite in = "sourcegraphic" in2 = "specout" operator = "arithmetic" k1 = "0" k2 = "1" k3 = "1" k4 = "0"/>     </filter>       

var svg=svg.selectall(".circle")       .data(this.data)       .enter().append("circle")       .attr("class", "circle")       .attr("r",function(d) {return r(math.sqrt( d[2]));})       .attr("cx", function(d) { return x(d[0]); })       .attr("cy", function(d) { return y(d[1]); })       .style("fill","blue");

how can add filter svg circle.

how can use filter effect in svg(d3). cani use directly or have change d3 format.

you have remove viewbox attribute first first svg, wrap around html , d3 can add svg tag containing animation. have add circles want attribute filter=url(#i1) told before.

i made codepen demonstrate how works this d3 example. take @ it, works perfectly.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
