This is an excerpt from an index.html of D3.js I have done, my idea is to include an external image and make it appear by clicking the 'btn3' button. In button 1 and 2 I have two graphs that work normally, the problem is to make button 3 display the image (of a link), D3.json is an example that I am trying to use for testing. Other options are welcome. Thanks for the help.

<button id="btn1">Sobreviventes e mortos por grupos</button>
<button id="btn2">Sobreviventes e mortos por porta de embarque</button>
<button id="btn3">Fotos</button>

You must specify image attributes separately, not batch. Noting that there was a function without closing:

d3.select("#btn3").on("click", function(){
    // Fazer com que o link abaixo funcione com o botão acima exibindo a imagem

    d3.json("http://www.reddit.com/r/earthporn.json?limit=80", function(error, imgs) {
        // filter out posts without a thumbnail
        var images = imgs.data.children.filter(function(d) {
            return d.data.thumbnail.slice(-3) == "jpg";
        });

        images.forEach(function(img) {
            d3.select("body")
            .append("a")
            .attr("href", img.data.url)
            .append("img")
            .attr("src",img.data.thumbnail)
            .attr("height","66")
        });
    }); // estava faltando esse fechamento       
});
