我想向svg元素添加工具提示。嘗試過基本的CSS和Javascript-有解無憂

我有一個學校專案，我必須制作一張“寶藏”地圖。我的想法是將世界地圖作為帶有國家和大陸的 SVG 元素。我得到了地圖，其中每個國家的邊界??都作為元素。我嘗試使用 vanilla CSS 創建工具提示，但沒有結果，并且在 google 上搜索了幾個用于工具提示的 javascript 和 jquery 解決方案，但沒有得到任何結果。我想知道它是否可能，因為我已經有點失去希望了。

我嘗試使用這段 jquery 作為工具提示

js檔案：

(function() {
var infoElem = $('.info');
infoElem.each(function() {
    var self = $(this),
        selfTooltiptext = self.data('tooltip-text');
    if (selfTooltiptext) $('<span/>', {class: 'tooltip', text: selfTooltiptext}).appendTo(self);
});

})();

html 中的 SVG 路徑：

<a href="#" class="info" data-tooltip-text="Hint">
    <path d="M1113.7 124.6l0.9 1-2.6 3.4 2.4 5.6-1.6 1.9-3.8-0.1-4.4-2.2-2.1-0.7-3.8 1-0.1-3.5-1.5 0.8-3.3-2.1-1-3.4 5.5-1.7 5.6-0.8 5.1 0.9 4.7-0.1z" id="EE" name="Estonia">
    </path>
        </a>

CSS：

.tooltip {
display: block;
position: absolute;
left: 0;
bottom: 120%;
width: 190px;
padding: 5px;
border-radius: 10px;
background-color: cadetblue;
color: #fff;
line-height: normal;
text-transform: none;
font-size: 12px;
opacity: 0;
transform: scaleY(0);
transition: all 0.2s ease;
}

.tooltip:after {
    position: absolute;
    content: '';
    left: 10px;
    bottom: -5px;
    width: 0;
    height: 0;
    border-top: 5px solid burlywood;
    border-right: 5px solid transparent;
    border-left: 5px solid transparent;
}

.info:hover .tooltip {
    opacity: 1;
    transform: scaleY(1);
}

您可以使用將<title>滑鼠懸停在特定區域上時彈出的系統 SVG 工具提示

當您將滑鼠懸停在地圖的某個區域時，它會放大并彈出帶有文本的工具提示
