本書旨在強(qiáng)調(diào)通過案例學(xué)習(xí)提高讀者自主學(xué)習(xí)能力，引導(dǎo)其通過知識點導(dǎo)讀、方法概要、系統(tǒng)介紹與導(dǎo)圖操作等內(nèi)容，循序漸進(jìn)地學(xué)習(xí)科學(xué)可視化的相關(guān)知識。本書具有以下特色。① 圖文并茂：知識點導(dǎo)讀、方法概要等部分，用大量圖示說明，直觀易懂。② 可操作性強(qiáng)：系統(tǒng)介紹、導(dǎo)圖操作等部分使學(xué)習(xí)者易于上手實踐和學(xué)習(xí)。③ 可擴(kuò)展性強(qiáng)：方便學(xué)習(xí)者在所提供的案例基礎(chǔ)上增加功能和擴(kuò)展應(yīng)用。
