Die steht vor der Tür und ist für den Zeitraum vom 2. bis 9. Oktober geplant. Kürzlich bin ich zufällig auf diese Nachricht gestoßen, die mein Interesse an Nobelpreisträgern und ihren Herkunftsländern geweckt hat. Bekanntgabe des Nobelpreises 2023 Diese Neugier führte mich zu der umfassenden Liste der Nobelpreisträger auf , die ich mithilfe von JavaScript in eine interaktive Tag-Wolke (oder ) umgewandelt habe, die eine elegante Möglichkeit bietet, die Länder mit der höchsten Anzahl an Nobelpreisträgern im Laufe der Geschichte zu erkunden und aufzudecken . Britannica Wortwolke Während dieses Prozesses wurde mir klar, dass diese Visualisierung als hervorragendes anschauliches Beispiel für ein Tutorial zum Erstellen interaktiver JS-basierter Tag-Clouds dienen könnte. Wenn Sie also meine Neugier auf Nobelpreisträger nach Ländern teilen, können Sie sich gleich unten auf etwas freuen! Und wenn Sie unbedingt erfahren möchten, wie ich diese Tag-Cloud zum Leben erweckt habe – und wie Sie somit Ihre eigene Tag-Cloud erstellen können – lesen Sie weiter! Schlagwortwolke der Nobelpreisträger nach Ländern Entdecken Sie die interaktive Version auf . CodePen A. Erstellen einer einfachen JS-Tag-Cloud Zuerst habe ich eine einfache JavaScript-Tag-Cloud programmiert. Wenn Sie Erfahrung mit der Erstellung von JS-Diagrammen haben, wissen Sie bereits, wie es funktioniert. Aber falls dies Ihr erstes Mal ist, beginnen wir mit den Grundlagen. Der Prozess lässt sich in vier grundlegende Schritte unterteilen: Erstellen eines Webcontainers Einschließlich JavaScript-Dateien Daten hinzufügen Schreiben von JS-Diagrammcode 1. Erstellen eines Webcontainers Ich habe eine einfache Webseite in HTML erstellt. Dort habe ich ein -Element hinzugefügt und ihm eine eindeutige ID gegeben – es ist der Ort, an dem die Tag-Cloud gezeichnet werden soll. Ich wollte, dass das Diagramm die gesamte Seite ausfüllt, also habe ich den entsprechenden CSS-Code mithilfe des -Tags hinzugefügt; Natürlich können Sie das nach Ihren Wünschen einstellen. <div> <style> <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"> <title>JavaScript Tag Cloud</title> <style type="text/css"> html, body, #container { width: 100%; height: 100%; margin: 0; padding: 0; } </style> </head> <body> <div id="container"></div> </body> </html> 2. Einbinden von JavaScript-Dateien Nachdem ich ein grundlegendes HTML-Seitenlayout fertiggestellt hatte, fügte ich die erforderlichen JavaScript-Dateien in den Abschnitt ein. <head> Es gibt viele , mit denen Sie Daten mit weniger Aufwand visualisieren können, als dies sonst erforderlich wäre. Ich habe mich für entschieden, das Tag Clouds sofort unterstützt, detaillierte Dokumente bereitstellt und für gemeinnützige Zwecke kostenlos ist. Wie auch immer, es ist nur ein Beispiel und die Grundlagen bleiben bei anderen Bibliotheken dieselben. JavaScript-Diagrammbibliotheken AnyChart Also habe ich die erforderlichen Skripte hinzugefügt. <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"> <title>JavaScript Tag Cloud</title> <script src="https://cdn.anychart.com/releases/8.11.0/js/anychart-core.min.js"></script> <script src="https://cdn.anychart.com/releases/8.11.0/js/anychart-tag-cloud.min.js"></script> <style type="text/css"> html, body, #container { width: 100%; height: 100%; margin: 0; padding: 0; } </style> </head> <body> <div id="container"></div> <script> // All the code for the tag cloud will come here. </script> </body> </html> 3. Daten hinzufügen Für diese Tag-Cloud habe ich Daten von übernommen. Vier Personen gewannen mehrmals den Nobelpreis: Frederick Sanger, Linus Pauling, John Bardeen und Marie Curie; Ich habe sie nur einmal gezählt. Einige Preisträger stammen aus zwei Ländern; Ich habe sie für beide gezählt. Britannica Die Daten mussten einige Änderungen vornehmen, bevor ich sie in die Wortwolke einspeisen konnte. Ich habe es in ein Array von Objekten mit vier Eigenschaften umgewandelt: – für den Namen des Landes x – für die Anzahl der Nobelpreisträger aus diesem Land Wert – für den Kontinent Kategorie – enthält einen Link zu Wikipedia für weitere Informationen. (Hinweis: Einige Länder, die zu Beginn des 20. Jahrhunderts existierten, sind heute andere Länder. Britannica speichert die ursprünglichen Ländernamen, was bei Wikipedia nicht immer der Fall ist, sodass die Gesamtzahlen nach Ländern etwas unterschiedlich ausfallen.)

Ich habe angefangen, die Funktion zu schreiben. anychart.onDocumentReady() <script> anychart.onDocumentReady(function () { // The tag cloud data and code will be in this section. }); </script> Darin habe ich die Daten aus dem vorherigen Schritt hinzugefügt, eine Tag-Cloud-Instanz erstellt, den Diagrammtitel festgelegt, auf die Containerelement-ID verwiesen und die resultierende Tag-Cloud gezeichnet. anychart.onDocumentReady(function () { // add data (copying from step 3) ... // create a tag cloud with the added data var chart = anychart.tagCloud(data); // set the chart title chart.title("Nobel Laureates by Country"); // set the container element id chart.container("container"); // initiate the drawing of the chart chart.draw(); }); So sah die ursprüngliche Tag-Cloud aus – die interaktive Version finden Sie auf .

Anpassen der JS Tag Cloud Nachdem ich diese grundlegende JavaScript-Tag-Cloud erhalten hatte, beschloss ich, einige Anpassungen hinzuzufügen, um die Diagrammansicht zu verbessern. 1. Ändern der Schriftart Zuerst habe ich die Schriftart geändert. Für die Titelanpassung habe ich HTML verwendet. chart .title() .enabled(true) .useHtml(true) .text( '<span style="font-size: 20px;">Nobel Laureates by Country</span>' ); Ich habe auch die Tags angepasst. chart .normal() .fontWeight(600) .fontVariant('small-caps'); 2. Den Winkel ändern Zweitens habe ich die Ausrichtung der Tags geändert, indem ich den Winkel auf Null gesetzt habe, damit sie alle horizontal angezeigt werden. chart.angles([0]); 3. Verbesserung des visuellen Erscheinungsbildes Drittens habe ich die Farben geändert und eine Farbpalette hinzugefügt. Ich habe mit der Funktion anychart.scales.ordinalColor() eine Farbskala erstellt und ihr ein Array von Farben übergeben. Dann habe ich die Farbskala auf das Tag-Cloud-Diagramm eingestellt und einen Farbbereich hinzugefügt. // create and configure a color scale let customColorScale = anychart.scales.ordinalColor(); customColorScale.colors(['#077fe8', '#1c9447', '#970fff', '#c47900', '#e80707','#323238']); // set the color scale as the color scale of the chart chart.colorScale(customColorScale); // get the color range let colorRange = chart.colorRange(); // enable the color range colorRange .enabled(true) .colorLineSize(15); 4. Verbesserung des Tooltips Viertens habe ich den Tooltip verbessert, einen Hinweis, der angezeigt wird, wenn Sie mit der Maus über die Wörter in einer interaktiven Tag-Cloud fahren. Ich habe auf die Funktion „tooltip()“ zugegriffen und die Funktion „format()“ verwendet, um den Inhalt des Tooltips zu ändern. chart .tooltip() .format('Total Nobel Laureates: {%value}\n Continent: {%category}'); 5. Hinzufügen von Interaktivität durch Link-Öffnung Schließlich habe ich beschlossen, einen Ereignis-Listener hinzuzufügen, sodass beim Klicken auf ein Land eine neue Seite mit weiteren Informationen geöffnet wird. Ich habe die Funktion listen() verwendet, um zu „hören“, wenn man auf das Tag eines Landes klickt. Als ich auf die URL-Eigenschaft im Datenarray zugreifen und die Funktion window.open() hinzufügen konnte, um die Webseite mit dieser URL zu öffnen. Ich habe auch die Eigenschaft _blank übergeben, um die URL in einem neuen Tab zu öffnen. chart.listen("pointClick", function(e){ var url = e.point.get("url").toString(); window.open(url, "_blank"); }); Nach all diesen Anpassungen habe ich am Ende eine coole, interaktive, JavaScript-basierte Tag-Cloud erhalten, die unten gezeigt wird. Es ist die endgültige Version der Tag-Cloud, mit der ich zufrieden war. Probieren Sie es mit dem vollständigen Quellcode auf aus und experimentieren Sie ruhig mit Farben, Interaktivität usw. – nutzen Sie Ihre ganze Kreativität und ich bin sicher, dass Ihnen der Prozess Spaß machen wird. CodePen Der Einfachheit halber füge ich unten auch den endgültigen JS-Tag-Cloud-Code ein. <html lang="en"> <head> <meta charset="utf-8"> <title>JavaScript Tag Cloud</title> <script

Ich hoffe, dass mein schrittweises Tutorial Ihnen dabei hilft, schnell eigene Diagramme dieser Art zum Laufen zu bringen. Hinterlassen Sie Ihre Fragen, falls vorhanden, in den Kommentaren und ich würde gerne einen Blick auf Ihre Tag-Clouds werfen!
