5. Labels
In the previous example we drew a simple bars chart using the D3.js's API.
Now we re-use the same source code of the previous example and add two features:
- Change bars' color with respect of the bars' height
- Add labels showing the value of each bar's datum
As in the previous example, click on the button below to change (randomly) the number of bars in the chart.
Remark: the SVG elements drawn here are rendered by some tiny CSS-like elements defined in the HMTL page,
which are not required to understand the concepts below. However, if you want to investigate also such style elements,
please have a look to the HTML source of this page.
