Les approchent à grands pas, prévues du 2 au 9 octobre. Récemment, je suis tombé sur cette nouvelle, suscitant mon intérêt pour les lauréats du prix Nobel et leurs pays d'origine. annonces du prix Nobel 2023 Cette curiosité m'a conduit à la liste complète des lauréats du prix Nobel sur , que j'ai transformée en un nuage de tags interactif (ou ) à l'aide de JavaScript, offrant un moyen élégant d'explorer et de découvrir les pays comptant le plus grand nombre de lauréats du prix Nobel à travers l'histoire. . Britannica nuage de mots Au cours de ce processus, il m'est apparu que cette visualisation pourrait servir d'excellent exemple illustratif pour un didacticiel sur la création de nuages de tags interactifs basés sur JS. Alors, si vous partagez ma curiosité pour les lauréats Nobel par pays, vous allez vous régaler juste en dessous ! Et si vous avez hâte de savoir comment j'ai donné vie à ce nuage de tags – et, par conséquent, comment vous pouvez créer le vôtre – continuez à lire ! Nuage de tags des lauréats du prix Nobel par pays Explorez la version interactive sur . CodePen A. Création d'un nuage de tags JS de base Au début, j'ai codé un nuage de tags JavaScript de base. Si vous avez de l'expérience dans la création de graphiques JS, vous comprenez déjà son fonctionnement. Mais si c'est votre première fois, commençons par les bases. Le processus pourrait être divisé en quatre étapes fondamentales : Création d'un conteneur Web Y compris les fichiers JavaScript Ajout de données Écrire du code de cartographie JS 1. Création d'un conteneur Web J'ai construit une page Web de base en HTML. Là, j'ai ajouté un élément et lui ai donné un identifiant unique — c'est l'endroit où le nuage de tags doit être dessiné. Je voulais que le graphique remplisse toute la page, j'ai donc ajouté le code CSS approprié en utilisant la balise ; bien sûr, vous pouvez définir cela à votre guise. <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. Inclure des fichiers JavaScript Une fois que j'ai terminé une mise en page HTML de base, j'ai inclus les fichiers JavaScript nécessaires dans la section . <head> Il existe de nombreuses qui peuvent aider à visualiser les données avec moins d'efforts que ce qui serait nécessaire autrement. J'ai opté pour , qui prend en charge les nuages de tags dès le départ, fournit des documents détaillés et est gratuit pour une utilisation à but non lucratif ; de toute façon, ce n'est qu'un exemple et les bases restent les mêmes avec les autres bibliothèques. bibliothèques de graphiques JavaScript AnyChart J'ai donc ajouté les scripts requis. <!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. Ajout de données Pour ce nuage de tags, j'ai pris les données de . Quatre personnes ont remporté le prix Nobel à plusieurs reprises : Frederick Sanger, Linus Pauling, John Bardeen et Marie Curie ; Je ne les ai comptés qu'une seule fois. Certains lauréats appartiennent à deux pays ; Je les ai comptés pour les deux. Britannica Les données nécessitaient quelques modifications avant de pouvoir les intégrer dans le nuage de mots. Je l'ai converti en un tableau d'objets avec quatre propriétés : — pour le nom du pays x - pour le nombre de lauréats du prix Nobel de ce pays valeur — pour le continent catégorie — contenant un lien vers Wikipédia pour plus d'informations. (Remarque : certains pays qui existaient au début du 20e siècle sont maintenant d'autres pays ; Britannica stocke les noms de pays d'origine, ce qui n'est pas toujours le cas sur Wikipédia, donc les décomptes totaux par pays sont un peu différents.)

Écrire du code de cartographie JS Enfin, j'ai ajouté quelques lignes de code JavaScript pour dessiner le nuage de tags lui-même. C'était assez simple. J'ai commencé à écrire la fonction . anychart.onDocumentReady() <script> anychart.onDocumentReady(function () { // The tag cloud data and code will be in this section. }); </script> À l'intérieur, j'ai ajouté les données de l'étape précédente, créé une instance de nuage de tags, défini le titre du graphique, référencé l'ID de l'élément conteneur et dessiné le nuage de tags résultant. 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(); }); Voici à quoi ressemblait le nuage de tags initial — la version interactive peut être trouvée sur .

Personnalisation du nuage de tags JS Après avoir obtenu ce nuage de balises JavaScript de base, j'ai décidé d'ajouter quelques personnalisations pour améliorer la vue du graphique. 1. Modification de la police Tout d'abord, j'ai changé la police. Pour la personnalisation du titre, j'ai utilisé du HTML. chart .title() .enabled(true) .useHtml(true) .text( '<span style="font-size: 20px;">Nobel Laureates by Country</span>' ); J'ai également ajusté les balises. chart .normal() .fontWeight(600) .fontVariant('small-caps'); 2. Changer l'angle Deuxièmement, j'ai modifié la façon dont les balises sont orientées en définissant l'angle sur zéro pour les afficher toutes horizontalement. chart.angles([0]); 3. Améliorer l'apparence visuelle Troisièmement, j'ai changé les couleurs et ajouté une gamme de couleurs. J'ai créé une échelle de couleurs à l'aide de la fonction anychart.scales.ordinalColor() et lui ai transmis un tableau de couleurs. Ensuite, j'ai défini l'échelle de couleurs sur le graphique du nuage de tags et ajouté une gamme de couleurs. // 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. Amélioration de l'info-bulle Quatrièmement, j'ai amélioré l'info-bulle, un indice qui apparaît lorsque vous survolez les mots dans un nuage de tags interactif. J'ai accédé à la fonction tooltip() et utilisé la fonction format() pour modifier le contenu de l'info-bulle. chart .tooltip() .format('Total Nobel Laureates: {%value}\n Continent: {%category}'); 5. Ajout d'interactivité avec l'ouverture de lien Enfin, j'ai décidé d'ajouter un écouteur d'événement afin qu'une nouvelle page s'ouvre pour fournir plus d'informations lorsque l'on clique sur un pays. J'ai utilisé la fonction Listen() pour « écouter » lorsqu'on clique sur le tag d'un pays. Quand j'ai pu accéder à la propriété URL dans le tableau de données et ajouter la fonction window.open() pour ouvrir la page Web avec cette URL. J'ai également transmis la propriété _blank pour ouvrir l'URL dans un nouvel onglet. chart.listen("pointClick", function(e){ var url = e.point.get("url").toString(); window.open(url, "_blank"); }); Après toutes ces personnalisations, j'ai fini par obtenir ci-dessous un nuage de tags sympa, interactif et basé sur JavaScript. C'est la version finale du nuage de tags dont j'étais satisfait. Découvrez-le avec le code source complet sur et n'hésitez pas à jouer avec les couleurs, l'interactivité, etc. - utilisez toute votre créativité et je suis sûr que vous apprécierez le processus. CodePen Pour votre commodité, je mets également le code final du nuage de balises JS ci-dessous. <html lang="en"> <head> <meta charset="utf-8"> <title>JavaScript Tag Cloud</title> <script

lauréats du prix Nobel par pays. J'espère que mon didacticiel par étapes vous aidera à mettre rapidement en place vos propres graphiques de ce type. Laissez vos questions dans les commentaires, le cas échéant, et j'aimerais consulter vos nuages de tags !
