CSS3已經開創了一種新的前端設計方式，可以用它來制作各種樣式的圖表。以下是一些關于如何用CSS3設計圖表的參考：

/*樣式一: 餅圖*/
.pie-chart {
width: 200px;
height: 200px;
border-radius: 50%;
overflow: hidden;
position: relative;
}
.pie-chart:before {
content: "";
width: 100%;
height: 100%;
border-radius: 50%;
position: absolute;
top: 0;
left: 0;
transform: rotate(0deg);
transform-origin: center center;
box-shadow: inset 0 0 0 100px #fff;
animation: rotate 5s linear forwards;
}
@keyframes rotate {
0% {
transform: rotate(0deg);
box-shadow: inset 0 0 0 100px #fff;
}
100% {
transform: rotate(360deg);
box-shadow: inset 0 0 0 100px #00bcd4;
}
}
/*樣式二: 柱狀圖*/
.bar-chart {
width: 400px;
height: 300px;
position: relative;
background-color: #F7F7F7;
}
.bar {
width: 50px;
position: absolute;
bottom: 0;
background-color: #00bcd4;
transition: height 1s ease;
}
.bar:first-child {
left: 50px;
}
.bar:nth-child(2) {
left: 150px;
}
.bar:last-child {
left: 250px;
}
.bar:hover {
height: 200px;
}
/*樣式三: 折線圖*/
.line-chart {
width: 400px;
height: 300px;
position: relative;
background-color: #F7F7F7;
}
.points {
display: flex;
justify-content: space-between;
position: absolute;
bottom: 0;
left: 0;
right: 0;
height: 250px;
}
.point {
width: 15px;
height: 15px;
border-radius: 50%;
background-color: #00bcd4;
position: relative;
}
.point:before {
content: "";
width: 2px;
height: 100%;
background-color: #00bcd4;
position: absolute;
bottom: -100%;
left: 50%;
transform: translateX(-50%);
}
.point:hover:before {
bottom: 0;
}
.line {
width: 2px;
background-color: #00bcd4;
position: absolute;
top: 0;
bottom: 0;
left: 50%;
transform: translateX(-50%);
z-index: -1;
}
.line:before {
content: "";
width: 100%;
height: 2px;
background-color: #00bcd4;
position: absolute;
top: 50%;
left: -50%;
}
.line:hover:before {
left: 0;
}

以上是三種樣式的圖表的CSS代碼，我們可以在HTML中引用，然后根據需要添加數據、樣式等，即可制作出個性化的、美觀的圖表。
