I am trying to create a word cloud using d3-cloud in my Angular2 application. However, I am struggling to find the correct typings to install. I attempted to use this package @types/d3.cloud.layout from npm but encountered an issue when importing it into my component - "Property layout could not be found in type". Can anyone assist me with resolving this problem?
I've discovered a workaround for achieving this task. Although not the recommended Typescript approach, I managed to do it using the fallback JS method. Here is the step-by-step guide:
import the d3 library as usual, but assign an alias to it: import * as D3 from 'd3'; (Take note: Capital D for D3)declare d3 once more so you can utilize it for WordCloud: declare let d3: any;D3 for all tasks related to the main d3 library and d3 specifically for word cloud generation.The typings for d3-cloud don't appear to be functioning correctly. Therefore, resorting to declare seems to be the only viable option at the moment.
Complete Code:
word-cloud.component.ts:
Updated implementation goes here...word-cloud.component.html:
<ng-content></ng-content>
word-cloud.component.scss:
.word-cloud {
Updated styles go here...
}
I was able to solve it by following these steps:
import * as d3 from "d3";
import * as d3Cloud from "d3-cloud";
wordCloud(): void {
let svg: any = d3.select("svg")
.attr("width", 850)
.attr("height", 350);
d3Cloud().size([800, 300])
.words(wordList)
}
