Now that you're getting comfortable writing JSX, you may be wondering how it differs from HTML.
|
||||
Ahora que te sientes cómodo escribiendo JSX, te preguntarás cuanto difiere de HTML.
|
||||
|
||||
So far, it may seem that HTML and JSX are exactly the same.
|
||||
Hasta ahora, puede parecer que HTML y JSX son exactamente iguales.
|
||||
|
||||
One key difference in JSX is that you can no longer use the word `class` to define HTML classes. This is because `class` is a reserved word in JavaScript. Instead, JSX uses `className`.
|
||||
Una diferencia clave en JSX es que ya no puedes usar la palabra `class` para definir clases HTML. Esto es debido a que `class` es una palabra reservada en JavaScript. En su lugar, JSX utiliza `className`.
|
||||
|
||||
In fact, the naming convention for all HTML attributes and event references in JSX become camelCase. For example, a click event in JSX is `onClick`, instead of `onclick`. Likewise, `onchange` becomes `onChange`. While this is a subtle difference, it is an important one to keep in mind moving forward.
|
||||
De hecho, la convención de nomenclatura para todos los atributos HTML y referencias a eventos en JSX se convierte a camelCase. Por ejemplo, un evento de clic en JSX es `onClick`, en lugar de `onclick`. Del mismo modo, `onchange` se convierte en `onChange`. Si bien se trata de una diferencia sutil, es importante tenerlo en cuenta de ahora en adelante.

|

|
||||
You can use HTML, JavaScript, CSS, and the D3 svg-based visualization library. The tests require axes to be generated using the D3 axis property, which automatically generates ticks along the axis. These ticks are required for passing the D3 tests because their positions are used to determine alignment of graphed elements. You will find information about generating axes at <https://github.com/d3/d3/blob/master/API.md#axes-d3-axis>. Required (non-virtual) DOM elements are queried on the moment of each test. If you use a frontend framework (like Vue for example), the test results may be inaccurate for dynamic content. We hope to accommodate them eventually, but these frameworks are not currently supported for D3 projects.
|
||||
Puoi usare HTML, JavaScript, CSS e la libreria di visualizzazione basata su svg D3. I test richiedono la generazione degli assi con la proprietà axis di D3, che crea automaticamente le tacche sugli assi. Queste tacche sono richieste per superare i test perché la loro posizione è usata per determinale l'allineamento degli elementi del grafico. Puoi trovare informazioni su come generare gli assi su <https://github.com/d3/d3/blob/master/API.md#axes-d3-axis>. Gli elementi del DOM (non-virtuale) richiesti sono selezionati al momento di ogni test. Se usi un framework frontend (come Vue per esempio) i risultati dei test potrebbero essere inaccurati per il contenuto dinamico. Speriamo di supportarli prima o poi, ma al momento non lo sono per i progetti D3.

D3 has several methods that let you add and change elements in your document.
|
||||
D3 ha diversi metodi che consentono di aggiungere e modificare elementi nel documento.
|
||||
|
||||
The `select()` method selects one element from the document. It takes an argument for the name of the element you want and returns an HTML node for the first element in the document that matches the name. Here's an example:
|
||||
Il metodo `select()` seleziona un elemento del documento. Esso richiede un argomento per il nome dell'elemento che si desidera e restituisce un nodo HTML per il primo elemento del documento che corrisponde a quel nome. Ecco un esempio:
|
||||
|
||||
```js
|
||||
const anchor = d3.select("a");
|
||||
```
|
||||
|
||||
The above example finds the first anchor tag on the page and saves an HTML node for it in the variable `anchor`. You can use the selection with other methods. The `d3` part of the example is a reference to the D3 object, which is how you access D3 methods.
|
||||
L'esempio precedente trova il primo tag di ancoraggio sulla pagina e salva un nodo HTML nella variabile `anchor`. È possibile utilizzare la selezione con altri metodi. La parte `d3` dell'esempio è un riferimento all'oggetto D3, che è il modo usato per accedere ai metodi D3.
|
||||
|
||||
Two other useful methods are `append()` and `text()`.
|
||||
Altri due metodi utili sono `append()` e `text()`.
|
||||
|
||||
The `append()` method takes an argument for the element you want to add to the document. It appends an HTML node to a selected item, and returns a handle to that node.
|
||||
Il metodo `append()` richiede un argomento per l'elemento che si desidera aggiungere al documento. Esso aggiunge un nodo HTML a un elemento selezionato e restituisce un handle (un appiglio) a quel nodo.
|
||||
|
||||
The `text()` method either sets the text of the selected node, or gets the current text. To set the value, you pass a string as an argument inside the parentheses of the method.
|
||||
Il metodo `text()` imposta il testo del nodo selezionato, o ottiene il testo corrente. Per impostare il valore, si passa una stringa come argomento all'interno delle parentesi del metodo.
|
||||
|
||||
Here's an example that selects an unordered list, appends a list item, and adds text:
|
||||
Ecco un esempio che seleziona una lista non ordinata, aggiunge un elemento alla lista e aggiunge del testo:

D3 allows you to chain several methods together with periods to perform a number of actions in a row.

D3 consente di concatenare diversi metodi tra loro con dei punti per eseguire un certo numero di azioni in una stessa riga.

D3 is about visualization and presentation of data. It's likely you'll want to change the styling of elements based on the data. You can use a callback function in the `style()` method to change the styling for different elements.
|
||||
D3 riguarda la visualizzazione e la presentazione dei dati. È probabile che tu voglia cambiare lo stile degli elementi in base ai dati. È possibile utilizzare una funzione di callback nel metodo `style()` per cambiare lo stile di diversi elementi.
|
||||
|
||||
For example, you may want to color a data point blue if it has a value less than 20, and red otherwise. You can use a callback function in the `style()` method and include the conditional logic. The callback function uses the `d` parameter to represent the data point:
|
||||
Ad esempio, potresti voler rendere blu un punto dati se ha un valore inferiore a 20, e rosso altrimenti. Puoi usare una funzione di callback nel metodo `style()` e includere la logica condizionale. La funzione callback utilizza il parametro `d` per rappresentare il punto dati:
|
||||
|
||||
```js
|
||||
selection.style("color", (d) => {

The `style()` method is not limited to setting the `color` - it can be used with other CSS properties as well.

Il metodo `style()` non si limita a impostare il `color` - può essere utilizzato anche con altre proprietà CSS.

Add the `style()` method to the code in the editor to set the `color` of the `h2` elements conditionally. Write the callback function so if the data value is less than 20, it returns red, otherwise it returns green.
|
||||
Aggiungi il metodo `style()` al codice nell'editor per impostare il `color` dell'elemento `h2` con la logica condizionale. Scrivi la funzione di callback in modo tale che se il valore dei dati è inferiore a 20, restituisca rosso, altrimenti restituisca verde.
|
||||
|
||||
**Note:** You can use if-else logic, or the ternary operator.
|
||||
**Nota:** È possibile utilizzare la logica if-else o l'operatore ternario.

A scatter plot is another type of visualization. It usually uses circles to map data points, which have two values each. These values tie to the `x` and `y` axes, and are used to position the circle in the visualization.
|
||||
Un grafico a dispersione è un altro tipo di visualizzazione. Di solito usa i cerchi per mappare i punti dati, e ogni cerchio ha bisogno di due valori. Questi valori si legano agli assi `x` e `y`, e vengono utilizzati per posizionare il cerchio nella visualizzazione.
|
||||
|
||||
SVG has a `circle` tag to create the circle shape. It works a lot like the `rect` elements you used for the bar chart.
