The invention discloses a gaph rendering method and device based on SVG. The method comprises the steps of obtaining a grid set of minimum grid units in site data of a to-be-rendered site; dividing the grid set into at least one grid subset according to the adjacent relation between the minimum grid units in the grid set; determining a pattern frame of a grid pattern corresponding to the grid subset according to the grid frame of the minimum grid unit in the grid subset; and rendering the grid graph according to the graph frame. According to the graph rendering method based on the SVG, the SVGis introduced as a bottom-layer graph rendering technology to achieve graph rendering of the minimum grid unit level, graph rendering is more mature and stable, learning cost is lower, the actual requirements of diversified service scenes can be met, and rendering efficiency is improved.
